Designed for active women who don’t want to sacrifice functionality for style, the Killtec KOW 11 WMN VST is a quilted sleeveless jacket built to effectively withstand winter conditions. Its unique quilting provides the volume and warmth needed for the cold season, while its technical windproof and water-repellent properties make it a versatile piece, suitable for both city life and the great outdoors. The Winter 2027 collection, of which it is a part, reaffirms a resolutely functional focus.

Protection from the elements: what the KOW 11 WMN VST actually offers

The jacket features a water-repellent treatment based on Teflon EcoElite™ technology, a plant-based, fluorine-free protective finish that repels water and water-based stains without using per- and polyfluoroalkyl substances. This more environmentally friendly approach is paired with a 10,000 mm water column rating, ensuring reliable protection against light to moderate precipitation. The jacket’s windproof design rounds out this package by minimizing heat loss in windy conditions—a feature that’s especially appreciated during winter outings.

Breathability and Everyday Comfort

To prevent moisture buildup under the jacket during strenuous activities, the KOW 11 WMN VST features a water vapor permeability rating of 3,000 g/m²/24 h. This level of breathability ensures proper temperature regulation during active movement by allowing sweat to escape to the outside. The adjustable hood adapts to your body shape and the conditions, offering additional protection against wind and rain without restricting mobility.

Design and Practicality

The center zipper features a chin guard, a detail that prevents uncomfortable chafing around the face. The two zippered side pockets and two interior pockets allow you to organize and securely store your everyday essentials. The jacket is also made from partially recycled material, consistent with the philosophy behind the chosen surface treatment technology. Care is simple: machine wash at 30°C; gentle tumble dry; do not bleach or dry clean.

The Killtec KOW 11 WMN VST women’s sleeveless jacket combines proven technical winter features with an eco-friendly surface treatment in a women’s sportswear garment available in sizes 38 through 44 in the color White Sand.
