Designed for active women in the mountains, the KSW 110 WMN LS SHRT is a long-sleeve T-shirt made of Powerstretch fabric, designed as a warm and breathable midlayer for winter sports and outdoor activities. Its role as a midlayer makes it a versatile piece, equally suited for snow sports and high-altitude outings in cold weather. KILLTEC has included it in its Winter 2027 collection with a technical design focused on freedom of movement and thermal comfort. It’s aimed at female athletes looking for a functional, lightweight base layer that’s easy to layer under a jacket or a thicker fleece.

Warmth and breathability thanks to the Powerstretch fabric

The Powerstretch fabric used in the KSW 110 WMN LS SHRT is designed to combine thermal insulation with moisture-wicking properties. Its four-way stretch structure allows the fabric to move with the body without creating resistance, while maintaining a warm layer around the torso and arms. The breathability of Powerstretch is a real advantage during sustained exertion: excess heat escapes, body moisture is managed, and comfort remains constant whether you’re stationary or on the move. This thermal profile makes it an effective midlayer as soon as temperatures drop.

Fit and Range of Motion

The stretchiness of the Powerstretch fabric ensures a full range of motion, without restricting movement at the shoulders or elbows. Whether you’re skiing, snowboarding, or enjoying any other winter activity, this long-sleeve T-shirt follows your every move without riding up or pulling. The fitted cut also allows for efficient layering under skiwear or outer layers, without adding unnecessary bulk. It feels comfortable right away, thanks to the fabric’s natural softness against the skin.

Features Designed for Winter Activities

Two design elements set this T-shirt apart from basic pieces. First, its high collar protects the nape of the neck and lower face from cold drafts—an area often exposed when the jacket is open or the neckline is insufficient. Second, the half-zip allows you to regulate ventilation based on the intensity of your activity: simply open it partially to release heat without having to take the shirt off. Together, these two details provide true versatility in changing conditions.

Environmental Commitment and Sustainable Treatment

The KSW 110 WMN LS SHRT benefits from the brand’s environmental approach, which has been in place for several years. The water-repellent treatment applied is PFC-free and compliant with the Teflon EcoElite™ finish from Chemours Company, made from 60% renewable plant-based raw materials. This treatment is biodegradable, GMO-free, and offers up to three times the durability of conventional non-fluorinated finishes. It also allows for 25% faster drying and low-temperature washing, which extends the garment’s lifespan. Furthermore, the KILLTEC apparel line has been GOTS-certified since 2021, ensuring rigorous standards throughout the entire textile production chain.

Versatile and technically advanced for its category, the KSW 110 WMN LS SHRT is ideal for female athletes seeking a breathable, stretchy, and comfortable midlayer—whether for a day on the slopes or a winter hike. Its high collar, half-zip, and Powerstretch fabric make it a logical choice whenever temperatures call for active thermal protection without added bulk.
