We asked women exactly what they wanted - then we built it. Our Jenny Collection was the world's first line of women's-specific vests, belts, and handhelds. Today our women's Vestas have become an integral part of the Signature Series, giving women exactly the right fit, feel and function.

Don't like waist packs? We don't either. So we designed the most comfortable, bounce-free waist storage you'll find. The Signature Series waistbelts ensure comfort is never compromised.

There's a reason so many runners are trying ski mountaineering - it's social, fun and expands possibilities. And it's simply the most fun way to enjoy the mountains in winter. From resort laps before work to high level races, skiers who use our vests benefit from the same Signature Series innovation as runners.
