Arc'teryx Kyanite

The Arc'teryx Kyanite Baselayer Bottom is a warm, movement-focused base layer designed for cold days and stop-and-start activities. Its Polartec Power Stretch Pro fleece delivers unrestricted stretch, while the soft brushed interior helps trap heat when temperatures drop.

A smooth nylon outer face layers comfortably beneath other garments, and the zippered thigh pocket keeps small essentials secure. It suits active users who want dependable warmth, flexible movement and comfortable next-to-skin performance.
