Snug fit that follows your movements like a second skin without constraint thanks to the elastane content.
This T-shirt can be worn in summer or winter under a long-sleeved jersey or windbreaker. 

A T-shirt for all seasons! 

The seamless technology uses knitted tube threads to avoid side seams and guarantee total comfort. 

Total comfort 

This T-shirt’s more ventilated areas under the arms, and on the chest and sides improve perspiration wicking and speed up drying. 

Stay dry during your runs and trail hikes. 

Perspiration is a natural reaction to heat and physical exertion.
Cotton T-shirts should be avoided: cotton absorbs moisture and rapidly cools the skin rather than transferring moisture outward and drying quickly. Choosing a T-shirt made of synthetic material helps you feel more comfortable during your session, regardless of how long it lasts. 

Why should I choose a running T-shirt made of synthetic fabric? 

When you find a good running and trail T-shirt, you want to hold onto it as long as you can. For this reason, it's crucial to wash your top correctly. 
- Wash it with other T-shirts and like clothes, but nothing with metallic parts (zips, buttons, etc.).
- Put it through a mild cycle (30°C) with just the right amount of washing powder.
- Do not machine dry or expose it directly to the sun: UV rays cause discolouring and damage the fabric.

Type of Length

Our jacket is equipped with a 2-layer membrane. The film applied to the inside of the fabric stops water coming from outside, but also wicks away perspiration. 
This ultra-technical component has a waterproof factor of 10,000 Schmerbers and can thus withstand the pressure exerted by 10,000 mm (400") of water.


Run in the rain without getting soaked!

The breathability of a product is measured by its Thermal Evaporative Resistance (TER).
The lower the resistance (and therefore the coefficient), the more breathable the fabric. Our waterproof jacket also has a breathability index that's lower than 6, so we can affirm it's definitely breathable... And that's just as well, because:why protect yourself from the water outside the jacket only to sweat more inside?

A breathable product for even greater comfort

To allow air to circulate freely, we've equipped this jacket with vents at the upper part of the back.

Discrete and effective ventilation points

The adjustable hood adapts to your body beautifully so that it follows your head movements.

Adjustable hood

Did you know that the intensity of your activity, the height profile, and the weather conditions should influence the choice of your different layers of clothing? 
This is the right order, which can be adjusted according to the parameters mentioned above:
- Layer 1 is breathable and wicks perspiration away to the other layers.
- Layer 2 is insulating, protects you from the cold and keeps you warm.
- Lastly, layer 3 protects you from the wind and/or rain.

stay dry with the 3-layer technique

Nathan, our designer, has left nothing to chance: from the design and choice of colour to the accessories and strategically-placed vents, each detail has been carefully designed and perfected! 
With its subtle and modern lines, and technical and precise finishes, this jacket combines technical quality with simplicity... Perfect for your runs, and much more!

A jacket that is as stylish as it is effective

We recommend that you machine wash on a synthetics programme (30°c), thorough rinse and slow spin.
Do not use bleach and softener to wash your jacket - gentle detergent is enough. 
Before washing your jacket, turn it inside out, empty the pockets and close the zippers as well as the hook and loop tabs on the wrists. 
Lastly, do not overload the machine, fold the garment, or mix colours.

Tips for washing your jacket

Dry your jacket in the open air, then 10 to 15 minutes in a tumble dryer, on a synthetics programme. It is vital that you do not overdry the jacket, or put it on a radiator.
If, in spite of the washing, thorough rinsing, open-air drying, and cool tumble drying, drops of water no longer flow across the surface of your jacket, we recommend that you rewaterproof it using a spray or a technical detergent sold in our stores

With this medium-support sports bra, you can give your all in moderate-impact activities, such as dancing, working out, cardio training, cycling, etc. while having optimal chest protection.

What activities is the medium-support muscle back seamless bra suitable for?

When playing, it’s essential you feel comfortable when moving. This means that you should choose clothing that makes it easier to move and take up postures. 
This sports bra has been designed with this in mind. We design a muscle back that will free up your shoulder blades so you have move freedom of movement for your arms.

How does the medium-support muscle back seamless bra provide freedom of movement?

You go all out, to the point where you are often fully covered in sweat at the end of a session. This isn’t always a very pleasant feeling, right? Well, thanks to this sports bra, you can say goodbye to moisture caused by sweat. The technical fabric can wick away sweat. It also dries faster to keep you dry. 
For greater efficiency, we also added a ventilated area between the breasts.

Stay dry, even when you are pushing yourself to the limit! How is this possible with the seamless, muscle-back, medium-support bra?

The running bra has two flexible single-thickness cups (no shell).

What type of cups does this medium-support muscle back seamless bra have?

Did you know that your breasts are supported almost exclusively by your skin? This makes them vulnerable and, during physical activies, the forces exerted on them are even higher than usual. The movements and bouncing they experience can make them up to five times heavier depending on the intensity of the sport. Wearing a sports bra will give you all the support, comfort, and protection you need. You are also protecting them from impacts, pain and premature sagging.

Why must your chest be supported during sport?

During sports, breasts experience forces that stretch the skin and ligaments of the chest. Lack of proper support can cause pain and premature sagging. However, too much support can also have negative consequences. The level of support your bra provides must be tailored to your bust size and the intensity of the impacts. 
The objective:To protect your chest while preserving the natural movement of the breasts.

What are the advantages of choosing between high, medium or low support?

Our labs test the models using a bust support test that measures the reduction in breast movement acceleration during sports activities. They are evaluated and then sorted into the following three levels: 1 for low support, 3 for medium support and 5 for high support.

How are the support levels of the Decathlon sports bras tested?

Depending on the type of sport you do, the support level of your bra will vary. We offer the following three options:
- Level 1: low support for activities that require slight chest movements (pilates, stretching, muscle strengthening, etc.); 
- Level 3: medium support for activities that cause moderate bouncing (dance, fitness, cardio-training, etc.); 
- Level 5: high support for activities that involve intense movements (step, treadmill, trampoline, etc.).

What sport should you associate with what level of support?

To keep your bust supported and comfortable, the bra size that you choose must be suit your body shape. This is how you do it:
- Stand opposite a mirror with a tape measure;
- Place it horizontally at the top of your back, on the lower part of your shoulder blades;
- Hold the tape over the largest part of the bust;
- Read the measurement without pulling the tape measure tight;
For greater accuracy, use our online calculator.

How do I measure the size of my bust to choose the right sports bra?

The sports bra comes in sizes ranging from XS to XL and is recommended for cup sizes up to a C cup.
The racer back spreads support evenly across the back. 
For D-cup and above, we have developed other, more suitable models.

What size of medium-support muscle back seamless bra should you choose?

Decathlon sports bras are designed to maximize comfort and prevent health problems. There reason there’s no underwire is to eliminate risks of injury and compression of the lymph nodes. The minimal seams at the nipple reduce irritation risks. By focusing on sweat-wicking fabrics, we can guarantee your comfort while significantly reducing the risk of skin irritation.

How are Decathlon sport bras designed?
