1. What is a fleece gilet and why choose one for outdoor adventures?

At its core, a fleece gilet is a sleeveless fleece jacket designed for outdoor activities and casual wear. It is engineered to provide thermal insulation directly to your torso, the part of your body where maintaining a stable temperature is most critical for overall comfort and physiological function. While a full-sleeved fleece jacket provides comprehensive warmth, the sleeveless design of a gilet offers mobility and temperature regulation. The decision between a fleece vest and a jacket for walking or hiking often comes down to the specific conditions and the intensity of the activity, with the gilet offering a level of adaptability that is hard to match.

The value of a fleece gilet is based in its deliberate simplicity and focus. By forgoing sleeves, it grants the wearer complete freedom of movement in the arms and shoulders, a necessary feature for activities ranging from scrambling up a rocky path to casting a fishing line or managing the reins on a horse.

Understanding the fleece gilet design

Utility is baked into the design of a quality fleece gilet. Typically, you will find a full-length front zipper, which allows for easy ventilation. This is useful during strenuous activity, as partially unzipping the gilet can rapidly release excess heat without the need to remove the entire top. Many designs, including the unisex gilets from Two Bare Feet, feature robust zips and a high collar that can be zipped up to protect the neck from chilly winds.

The armholes are designed to be large enough to allow for a full range of motion and to fit comfortably over other layers, such as a base layer or a light shirt, without bunching or feeling restrictive. This is key to the gilet’s versatility, allowing it to function as part of a sophisticated layering system or as a standalone piece.

The science behind fleece materials

The term “fleece” refers to a synthetic fabric, typically made from polyethylene terephthalate (PET) or other polyester fibres. Its invention was a breakthrough in outdoor clothing, offering a lightweight, breathable, and highly effective alternative to traditional materials like wool.

The material’s structure is key to its performance; it is a soft, napped fabric (i.e. it has a fuzzy surface) with a deep pile that creates thousands of tiny air pockets. These pockets trap air, which is then warmed by your body heat, creating an insulating layer that is efficient for its weight. This means a gilet can provide substantial warmth without the burden of a heavy jacket.

A common metric for fleece quality and warmth is its weight, measured in grams per square metre (gsm). A 300gsm fleece gilet, like those in the Two Bare Feet range, offers a significant degree of warmth, placing it in the mid-to-heavyweight category, perfect for cool British autumn days or as a robust mid-layer in winter.

One of the properties of polyester is that is hydrophobic. This means a fleece is good at repelling water and dries very quickly when it does get wet, a considerable advantage over materials like cotton which absorb moisture and lose all insulating properties. Modern fleece fabrics are also engineered for excellent breathability, actively wicking moisture away from the skin to the outer surface of the fabric where it can evaporate, keeping you dry and comfortable during exertion.

2. Core temperature regulation

The single most important function of a fleece gilet is regulating core body temperature. By focusing insulation on the torso, where your vital organs are located, a gilet helps efficiently maintain the body’s natural heat balance.

When your core is warm, your body does not need to work as hard to pump warm blood to your extremities, meaning your hands and feet are more likely to stay warm as well. In variable weather or during activities with fluctuating intensity levels, such as hiking up a steep incline followed by a rest on a breezy summit, a gilet allows you to manage your temperature well. It keeps the chill off when you are static but prevents the rapid overheating that can occur with a full-sleeved jacket when you are on the move.

Why core warmth matters in outdoor activities

When the body’s core temperature drops, it can lead to impaired coordination, poor decision-making, and, in severe cases, hypothermia. The body will prioritise keeping the vital organs warm by reducing blood flow to the limbs, which is why your fingers and toes are often the first things to feel cold.

A fleece gilet safeguards your core against the cold. This allows your circulatory system to function optimally, ensuring muscles get the oxygen they need and your extremities are not left struggling.

Freedom of movement vs full-sleeve alternatives

While a fleece jacket is an excellent piece of kit, its sleeves can sometimes be a hindrance, depending on what you are doing. The true advantage of the gilet becomes apparent in activities that demand unimpeded upper body movement. Consider the fluid, repetitive motion required for paddling a kayak or canoe; sleeves can chafe, restrict movement, and cause overheating. Similarly, for a climber reaching for the next handhold or an equestrian guiding their horse, complete arm movement freedom is necessary.

A gilet eliminates restriction. It allows your arms to move naturally while keeping your torso warm and comfortable. This makes it a superior choice for a wide array of dynamic pursuits, including cycling, running, and even practical outdoor tasks like setting up camp or chopping wood.

3. Versatility: from trail to town

One of the most compelling attributes of the modern fleece gilet is its remarkable versatility. The clean lines and practical design mean it transitions effortlessly from rugged outdoor environments to more casual, everyday settings. A well-designed gilet no longer looks out of place over a shirt for a trip to the pub garden or as an extra layer for a chilly morning commute.

The adaptability makes it a cost-effective component of any varied outdoor wardrobe. Our unisex fleece gilet, for instance, is designed to be just as functional on a windswept trail as it is practical for running errands in town on a cool day. It offers a sporty yet understated aesthetic that pairs well with walking trousers, jeans, casual chinos, or underneath a changing robe, ensuring you are prepared for whatever the day holds.

Seasonal adaptability throughout the year

A fleece gilet is not confined to a single season. On a cool spring morning or a breezy summer evening, it can be worn as a comfortable outer layer over a t-shirt or long-sleeved top, providing just the right amount of warmth without causing you to overheat.

As autumn arrives and the air turns crisp, a gilet becomes the ideal companion for countryside walks and outdoor work. When winter sets in, it transforms into an essential mid-layer, fitting neatly under a waterproof or insulated jacket to boost core insulation without bulky, restrictive sleeves. This year-round utility ensures that a fleece gilet is one of the most practical and frequently worn items you can own.

The unisex advantage for outdoor enthusiasts

A unisex fit is often designed to be slightly more relaxed, accommodating a wide range of body shapes and allowing for comfortable layering underneath. This potentially simplifies the purchasing process and offers great value for families or couples who may wish to share gear.

By adopting a unisex design with our gilets, Two Bare Feet ensures the focus remains on performance, comfort, and durability for all wearers. The cut is carefully developed to provide a flattering and functional fit for everyone, removing barriers and making high-quality outdoor gear more accessible.

4. How fleece gilets excel in layering systems

The concept of a layering system is the cornerstone of dressing effectively for the outdoors. The goal is to create a “microclimate” around your body that you can easily adjust by adding or removing layers in response to changing weather conditions and your own activity level. A fleece gilet is a perfect component for a layering system due to its low bulk and targeted insulation.

A typical three-part system consists of:

  • a base layer to wick moisture
  • a mid-layer for insulation
  • an outer shell for protection from wind and rain.

A fleece gilet excels as a mid-layer, providing warmth without impeding breathability. A 300gsm fleece gilet, for example, is substantial enough to make a real difference in cold conditions, yet the garment remains packable and lightweight.

As a mid-layer in cold conditions

In cold, damp, or windy weather, a fleece gilet truly comes into its own as a mid-layer. Worn over a technical base layer (such as merino wool or a synthetic equivalent) and under a waterproof shell jacket, it creates a highly effective thermal barrier. The base layer pulls sweat away from your skin, the gilet traps a layer of warm air around your core, and the shell protects you from the elements.

This arrangement is far more adaptable than wearing a single, heavy insulated jacket. If you start to overheat while climbing a steep hill, you can unzip your shell jacket and the gilet for ventilation. If the sun comes out but the wind remains cold, you can remove the shell and continue with just the gilet. This ability to fine-tune your insulation is what keeps you comfortable and dry, preventing the cycle of sweating during exertion and then getting cold during periods of rest.

As an outer layer in mild weather

On cool, dry days, particularly during activities that generate a lot of body heat, a fleece gilet functions perfectly as an outer layer. For a brisk autumn walk, a spring cycle ride, or outdoor gardening, it provides the ideal balance of warmth and ventilation. It keeps the chill from your torso while your arms remain free and uncovered, allowing excess heat and perspiration to dissipate easily.

In this scenario, it offers a level of comfort that a full jacket cannot. It prevents that clammy, “boil in the bag” feeling that can occur during high-output activities, ensuring your body’s temperature remains stable.

Pairing with base layers and shells

To maximise the effectiveness of your fleece gilet, pairing it with the right companion layers is essential. For a base layer, choose a material that is highly effective at wicking moisture. Synthetics (like polyester) and merino wool are excellent choices. Avoid cotton at all costs, as it absorbs sweat, stays wet, and will make you cold the moment you stop moving.

Your choice of outer shell should be dictated by the conditions. For dry but windy days, a lightweight, packable windbreaker is a perfect partner for your gilet. It will stop the wind from stripping away the warm air trapped in the fleece fibres. For wet weather, a fully breathable and weatherproof exterior is necessary. Look for a shell with a fit that comfortably accommodates the gilet underneath without feeling tight or compressed, as this can reduce the fleece’s insulating ability.

5. Activity-specific benefits: from hiking to daily dog walks

The advantages of a fleece gilet are best understood through use across a range of real-world activities. The unique combination of features makes a gilet perfectly suited to the specific demands of outdoor pursuits.

Trail walking and hiking

British trails often involve varied terrain and sudden changes in weather, making temperature regulation a constant challenge. A gilet allows for easy adjustments on the move. When tackling a strenuous ascent, its breathability and sleeveless design help prevent overheating. During a rest stop in an exposed area, it provides essential core warmth against the wind. In addition, practical features like zipped pockets are perfect for keeping essentials like a phone, compass, or snacks secure and easily accessible. Its low weight and packability also mean it can be stowed in a backpack with minimal issues when not in use.

Cycling and active sports

In cycling, maintaining a warm core while managing the intense heat generated by exertion is crucial. A fleece gilet is an ideal solution, particularly for rides in cool or changeable conditions. It shields the torso from wind chill—a significant factor when moving at speed—without causing the arms and underarms to overheat. The total arm movement gilet design allows is also essential for safe and comfortable bike handling. This same principle applies to a host of other active sports, from running and jogging on cold mornings to climbing, where unrestricted shoulder and arm movement is a non-negotiable requirement. For equestrians, a gilet can be worn over show shirts or base layers, providing warmth without interfering with control of the reins.

Casual outdoor activities and everyday wear

A fleece gilet is outstanding for more relaxed outdoor activities. For the daily dog walk, it offers the perfect level of warmth for all but the most extreme weather, and its durable, low-maintenance nature means it can handle a bit of mud. The best dog walking gilet is one that is warm, comfortable, and has good pockets for treats and bags. It is equally suited to gardening, visiting an outdoor market, or simply enjoying a coffee outside. Its effortless style and practicality make it a go-to choice for anyone leading an active, outdoor-oriented lifestyle.

Of course, when the conditions deteriorate, a fleece gilet can also be layered under a reliable exterior shell, such as a dog walking changing robe.

6. Essential features to look for in quality fleece gilets

While all fleece gilets share a basic design, the details and quality of construction can vary significantly. When choosing a gilet, paying attention to specific features will ensure you get a garment that performs well and lasts for years.

Pockets and storage

Practical and secure storage is a vital feature for any piece of outdoor clothing. Look for a gilet with at least two zipped exterior pockets for your hands. Zips are essential to ensure that your valuables, such as keys, a phone, or a wallet, do not fall out while you are active. The placement of the pockets is also important; they should be positioned for easy access without interfering with, for example, a backpack hip belt.

Adjustability for a custom fit

A gilet that can be adjusted to your body and layering system offers superior performance. A key feature to look for is an adjustable hem, usually with an elasticated drawcord and toggles. Cinching the hem tight can dramatically reduce heat loss and prevent cold drafts from entering from below. This also allows you to customise the fit, making it snugger when worn as a mid-layer or looser when worn over a thick jumper.

Details that make a difference

The overall durability and feel of a gilet are often determined by the finishing touches. High-quality zips from a reputable manufacturer are a good indicator. A fleece-lined collar and soft finishing can prevent chafing and add a touch of comfort. Details such as stylish binding on the armholes and hem, or a discreetly embroidered logo, can elevate the look of the gilet and speak to the brand’s attention to detail.

The Two Bare Feet unisex gilet

Putting all these principles into practice, the Two Bare Feet Unisex Full Zip Fleece Gilet is the ideal embodiment of a modern, high-performance bodywarmer. Crafted from a substantial 300gsm fleece, it provides an excellent level of warmth while remaining soft to the touch. It is a true workhorse garment, designed to deliver reliable comfort season after season.

The gilet incorporates essential features for outdoor practicality, including two secure zipped hand pockets and an adjustable drawcord hem to lock in warmth and perfect the fit. The design is enhanced by thoughtful finishing touches; stylish faux leather binding on the armholes provides a durable and clean finish, while a subtle, tonal embroidered logo on the chest signifies quality without being obtrusive.

Available in two versatile and classic rich colours, both our marine blue and khaki gilets are the perfect choice for staying warm while looking great – whether you are embarking on your next coastal adventure, or perfectly at home on countryside trails, at the stables, or around the campsite.

7. Maintaining your fleece gilet

A high-quality fleece gilet is a durable piece of equipment, but proper care will extend its life and maintain its performance. Fleece is generally a very low-maintenance fabric, which is another of its key advantages.

Washing and drying best practices

Before washing, it is always best to check the care label. As a general rule, turn the gilet inside out and close all zippers to protect them and prevent snagging. Wash it in a machine on a cool or warm cycle with a mild detergent. It is very important to avoid using fabric softeners or bleach, as these can clog the fibres of the fleece, which will reduce its breathability and insulating properties.

Fleece dries remarkably quickly. For best results and to conserve energy, air-drying is recommended. Simply hang it on a line or lay it flat. If you are in a hurry, you can tumble dry it on a low heat setting. High heat can damage the synthetic fibres, so it should be avoided. Following these steps will help prevent pilling and ensure the fleece retains its loft and softness.

Storage and seasonal maintenance

Storing your fleece gilet correctly will ensure it is ready to go when you need it. Make sure the garment is completely clean and dry before putting it away for an extended period to prevent mildew. It is best to store it by hanging it in a wardrobe or folding it loosely in a drawer. Avoid compressing it tightly for long periods (for instance, in a vacuum-sealed bag), as this can flatten the fleece fibres and reduce their ability to trap insulating air. Thanks to its low bulk, it packs down easily into a bag for transport on any trip.

8. Selecting your ideal fleece gilet

Choosing the right fleece gilet ultimately comes down to your individual needs, the activities you plan to use it for, and your personal style. By considering a few final factors, you can choose one that will become a consistent go-to on your outdoor journeys.

Colour considerations for outdoor use

While colour might seem like a purely aesthetic choice, it can have practical implications. Brighter colours like red, orange, or light blue can offer better visibility, which is a safety consideration in mountainous or remote areas. For general use, more neutral and earthy tones like khaki, marine blue, or charcoal are incredibly versatile. They are less likely to show dirt and can be easily paired with other items in your wardrobe, making them excellent choices for those who want a gilet that performs on the trail and looks great in town.

Fit and sizing for maximum comfort

Getting the right fit is crucial for both comfort and performance. Consider how you intend to use the gilet most often. If you plan to wear it primarily as a mid-layer under a snug-fitting waterproof jacket, you may want a slightly closer, more athletic fit. If you see it more as an outer layer to be worn over jumpers and shirts, a slightly more generous fit might be preferable. Always consult the brand’s sizing chart and consider taking measurements to ensure the best possible fit. A well-fitting gilet should allow for a full range of motion in the shoulders and not feel restrictive across the chest or back.
