FRAM Running Clothing — for City Training and Trail Running

The right running clothing helps you stay comfortable during workouts in different weather conditions and at different levels of intensity. Unlike everyday clothing, functional running apparel should effectively manage moisture, dry quickly, allow unrestricted movement, and add as little unnecessary weight as possible.

Your equipment also depends on where you run. For a short city workout, a T-shirt, shorts, and running socks may be enough. Trail running and longer runs over rough terrain require a more comprehensive system that can include a running vest for water and essential gear, protection from wind and precipitation, a buff, gaiters, and other accessories.

Regardless of the type of training, good sportswear for running should combine several key characteristics: lightweight construction, ventilation, moisture wicking, quick-drying fabric, breathable materials, and an ergonomic fit.

What Clothing and Gear Do You Need for Running?

Running equipment should be considered as a system that changes depending on distance, weather, terrain, and how self-sufficient you need to be on the route.

For regular training, runners use functional T-shirts and long sleeves, shorts or tights, running socks, windbreakers, and waterproof membrane jackets. In cold weather, insulating layers, gloves, and buffs can be added.

On longer distances and during trail running, carrying equipment becomes another consideration. A running vest allows you to carry water, nutrition, a first aid kit, additional clothing, and other essentials. Trekking poles may be useful on demanding terrain, while gaiters help prevent stones, dirt, snow, and trail debris from getting inside your shoes.

Running in the City

For city training, a minimal equipment setup is usually enough.

In summer, the basic kit consists of a lightweight functional T-shirt, shorts, and running socks. In cooler weather, you can replace the T-shirt with a long sleeve or add a windbreaker. In winter, several thin layers can be combined depending on the temperature and intensity of your workout.

Because water, shelter, and a way home are usually relatively easy to access during an urban run, there is often no need to carry a large amount of equipment.

Trail Running and Running on Rough Terrain

Trail running places greater demands on both clothing and equipment.

Climbs and descents constantly change the intensity of your effort, forest sections alternate with exposed ridges, and temperature, wind, and precipitation can change considerably during a single route.

The longer and more remote the route, the more important self-sufficiency becomes. You may need to carry water and nutrition, a first aid kit, a windbreaker or membrane jacket, trekking poles, and other essential equipment.

For running over rough terrain, the functionality of each individual item matters, but so do the low weight and compact size of the entire kit.

Running in Summer and Winter

Running Clothing for Summer

In summer, the primary purpose of running apparel is to help the body release excess heat and manage moisture efficiently.

A lightweight functional T-shirt and running shorts can form the basis of the kit. In strong sun or on overgrown trails, a thin long sleeve can provide additional coverage for the arms without adding significant insulation.

Fabrics should effectively move moisture away from the body and dry quickly. This is why functional synthetic materials are generally more practical for intense running than ordinary cotton, which absorbs a lot of moisture and stays wet for longer.

Even in warm weather, trail runners should be prepared for changing conditions. A compact windbreaker or membrane jacket may be useful on exposed terrain, in strong winds, or when precipitation begins.

Running Clothing for Winter

The main principle of winter running is to stay warm without overheating.

Your body generates a significant amount of heat during intense activity, even when the temperature is below freezing. If you dress too warmly, your clothes can quickly become wet from perspiration. When your pace decreases or you stop, that moisture can contribute to rapid cooling.

Several functional layers therefore work better than one very warm layer.

A long sleeve that moves moisture away from the body can serve as a base layer. Additional layers are selected according to the temperature, wind, and intensity of the workout. A windbreaker protects against cold air, while a membrane jacket becomes useful when wind is accompanied by rain, snow, or wet snow.

A buff can protect the head, neck, and face, while gloves keep the hands protected from cold and wind. For winter trail running, gaiters can also help prevent snow from getting inside your shoes.

Running Gear

Running Vests

On longer distances, you need a practical way to carry essential equipment. This is the purpose of a dedicated running vest.

Its pockets and compartments can hold water, energy gels and other nutrition, a first aid kit, additional clothing, and small pieces of equipment. The design may also include attachments for carrying trekking poles.

Unlike a conventional backpack, a running vest fits closely around the torso. This helps reduce bouncing while running and distributes the load more evenly around the body.

One of the most important features is quick access to essential items without having to stop. Front pockets allow you to reach water, gels, and other frequently used items while moving.

When choosing a running vest, pay attention to:

• capacity and number of compartments;

• fit and adjustability;

• pocket placement;

• compatibility with soft flasks or a hydration system;

• trekking pole attachments;

• overall weight;

• back ventilation;

• stability and minimal bouncing while running.

The capacity you need primarily depends on the distance and how self-sufficient you need to be. A short training session may require only enough space for water and nutrition, while a long mountain route can require additional water, food, a first aid kit, spare clothing, and other mandatory or essential equipment.

Running Clothing

Running T-Shirts

A T-shirt is a fundamental piece of summer running clothing and one of the most important layers for high-intensity training.

The main requirement for a running T-shirt is effective moisture management. The fabric should move moisture away from the skin, spread it over a larger surface area, and help it evaporate quickly.

Functional synthetic materials such as COOLMAX® are well suited to this purpose. This type of fabric combines moisture-wicking performance, quick drying, and low weight, making it suitable for intense physical activity.

An ergonomic fit is equally important. A running T-shirt shouldn't restrict movement or create excessive friction, particularly around the shoulders and underarms.

When choosing a running T-shirt, pay attention to moisture wicking, drying speed, breathability, weight, fit, and comfort during prolonged activity.

Running Long Sleeves

A functional long sleeve performs the same basic tasks as a running T-shirt while providing additional coverage for the arms.

Long sleeves made from COOLMAX® and other quick-drying synthetic materials work well for running because they help manage moisture while remaining lightweight enough for active movement.

A long sleeve can be worn as the main layer in cool weather or as a base layer during winter training.

In summer, a lightweight model can also provide additional coverage from the sun, vegetation, and insects during trail running.

When choosing a running long sleeve, look for breathable material, quick-drying performance, stretch, low weight, and freedom of movement.

Running Windbreakers

The main purpose of a running windbreaker is to protect against wind without adding significant weight to your kit.

These jackets are typically made from lightweight synthetic fabrics with a dense weave or additional wind-resistant treatment.

The balance between wind protection and breathability is particularly important. Running generates a lot of body heat, so a fabric that blocks airflow too completely can cause moisture and heat to accumulate inside the jacket.

Ventilation features can help release excess heat and improve comfort during high-intensity movement.

Packability is another important characteristic. A lightweight windbreaker should take up minimal space when folded so it can be carried in a running vest when it isn't needed.

When choosing a running windbreaker, consider weight, wind resistance, ventilation, breathability, packability, and ergonomic fit.

Membrane Jackets for Running

When you need protection not only from wind but also from rain or wet snow, a membrane jacket becomes the more appropriate outer layer.

Compared with an ordinary windbreaker, a waterproof membrane provides a significantly higher level of protection against precipitation. At the same time, breathability is particularly important for running because the body produces a large amount of heat and moisture during intense activity.

A running membrane jacket should therefore combine reliable waterproof protection with the highest practical level of breathability for its intended use.

Lightweight membrane fabrics are typically used for this type of jacket, while the construction may incorporate additional ventilation features.

Packability also matters. During trail running, a membrane jacket may spend a large part of the route inside your running vest and only be used when the weather deteriorates.

When choosing a membrane jacket for running, pay attention to waterproof performance, breathability, ventilation, weight, packability, hood design, and freedom of movement.

Running Socks

Socks may be a small part of your running kit, but they can have a major impact on comfort, particularly over long distances.

Their main tasks are to manage moisture, reduce friction, and keep your feet comfortable throughout the workout.

Running socks are commonly made from synthetic fibers and blends that move moisture and dry faster than ordinary cotton.

Their construction may use different densities in specific areas of the foot, elastic support, and ventilation zones.

For trail running, a secure fit is particularly important. Socks shouldn't slide or bunch up during long climbs and descents.

When choosing running socks, consider moisture management, quick drying, fit, ventilation, seam placement, and resistance to friction.

Running Accessories

Buffs

A buff is one of the most versatile accessories in a running kit.

In cool weather, it can protect your neck and face from cold air and wind. When necessary, it can also be worn as a lightweight head covering or headband.

For running, lightweight and stretchy synthetic fabrics are particularly practical because they manage moisture, dry quickly, and take up very little space.

In summer, a thin buff can provide additional protection from the sun. In winter, it can be used as an extra layer for protection against cold.

Running Gloves

Your hands can feel cold even when your core is already warm from running.

That's why lightweight gloves are often one of the first accessories added to a running kit as temperatures begin to fall.

For active movement, breathability is just as important as insulation. Gloves that are too warm can quickly become damp from perspiration.

Lightweight synthetic and Softshell materials are well suited to running gloves because they can provide a balance of protection from cold air and wind while allowing moisture and excess heat to escape.

In lower temperatures, models with additional insulation can be used.

Gaiters for Trail Running

Gaiters are particularly useful for trail running.

They cover the upper part of the shoe and help prevent small stones, sand, dirt, twigs, snow, and other trail debris from getting inside.

Running gaiters should be lightweight, fit securely around the shoe, and allow unrestricted movement of the ankle.

For dry summer routes, lightweight breathable synthetic fabrics are usually sufficient. For snow and wet conditions, materials with better moisture protection may be more appropriate.

Gaiters are particularly useful on loose trails, mountain terrain, snow, and long-distance routes where even a small stone inside your shoe can quickly become a significant source of discomfort.

How to Choose Running Clothing and Gear

There is no single running clothing setup that will work equally well for a short summer run in the city, a winter training session, and a multi-hour mountain trail.

Start by considering the conditions in which you plan to run.

For short city runs, a basic kit is usually enough: a functional T-shirt or long sleeve, shorts or tights, and running socks. A windbreaker or membrane jacket can be added according to the weather.

For summer running, prioritize lightweight construction, ventilation, moisture wicking, and quick drying.

For winter running, build a layering system that provides protection from cold and wind without causing overheating. A buff and gloves can be added to protect exposed areas.

For trail running, consider not only the temperature at the start but also the duration of the route, elevation gain, weather forecast, terrain, and distance between points where you can replenish your supplies.

On longer routes, a running vest allows you to carry water, energy gels, a first aid kit, additional clothing, and essential equipment. A windbreaker or membrane jacket provides protection when the weather changes, while gaiters can improve comfort on loose, snowy, or debris-covered terrain.

When choosing running apparel, sportswear for running, and trail running gear, consider the entire kit as a system rather than focusing on a single feature. Quick-drying fabric, ventilation, moisture wicking, low weight, an ergonomic fit, and breathable materials help maintain comfort during movement, while properly selected equipment allows you to carry everything you need for a particular distance.

FRAM running clothing can be combined according to the season, type of training, and difficulty of the route — from a lightweight setup for a city run to a complete system for long-distance trail running in the mountains.
