Women's Technical Trail Underwear
Our page Women's Technical Sports Underwear brings together our tips for choosing body-hugging outfits: high-support bras for descents, seamless technical pants, vests, and base layer tops, made from merino wool or synthetic fibres, for running dry and without discomfort.
Support and comfort, with every stride.
The essential sports bra
For female runners, the sports bra is the most important piece of underwear. On the trails, the descents cause multiple impacts and movements of the breasts, which can lead to pain and eventually stretch the tissues. A high-support bra, with wide straps, a racerback or crossed back, and a firm underband, reduces these movements. It's important to choose the right size: too loose, it won't provide support; too tight, it restricts breathing.
The other clothing
Women's trail wear also includes:
- Tops and T-shirts.
- Jackets and Windbreakers.
- Shorts and Tights.
- Trousers and Leggings.
- Sweatshirts.
- Socks and Ankle Socks.
All the clothing can be found on the women's clothing page.
Wicking moisture
Like any base layer, trail underwear must wick away sweat to keep the skin dry and prevent cooling at the top or during breaks. Sports bras and pants made from synthetic fibres dry very quickly; those made from merino wool regulate temperature and limit odour, which is a plus for multi-day races. Tight-fitting tank tops and body shirts complement the base layer in cooler weather.
No seams or chafing
On long distances, friction becomes the main enemy: seams, elastics, and labels irritate the skin over hours, especially with a hydration pack whose straps press on the shoulders. Models that are seamless or have flat seams, with soft elastics, prevent these irritations. Always test your outfit on a long run before a race. Wash your technical underwear at thirty degrees, in a mesh bag, without fabric softener.
Good deals
Great bargains can also be found in good deals, promotions, clearance, sales, and Black Friday. The new arrivals showcase the latest collections, and items shipped within 24h are prepared and sent within 24 hours. The key events of the year occur in a consistent order: Black Friday at the end of autumn, the holiday season, winter sales, spring’s French Days, followed by summer sales and back-to-school time.
Frequently asked questions
How to choose the size of your trail sports bra?
Measure your underbust and bust, then refer to the guide. Do the jump test: your breasts should move as little as possible, without the straps digging into your shoulders.
When should you replace a sports bra?
As soon as the elastic stretches or the support decreases during descents. A bra that is worn and washed very often gradually loses its support, even if it still looks good.
What kind of panties should you wear for long runs?
A technical seamless panty, made from synthetic fibres or merino, dries quickly and doesn’t chafe. It should stay in place without being too tight, to avoid irritation on long outings.
Tank top or long sleeves as a base layer?
The tank top is suitable for warm outings and keeps the shoulders free. In winter or at altitude, a long-sleeve merino top retains warmth even when wet and protects against wind.
How to care for a sports bra to maintain its support?
Wash it in a mesh bag, on a delicate cycle and at a low temperature, with hooks closed. Avoid tumble drying: heat relaxes the elastic fibres responsible for support.
