Light & Packable Protection
When you need to stay quick on your feet through stretches of blustery breezes and spotty showers, slip on the ultralight construction and weather-repelling protection of the Ventum Ultralight K4 Pant. Top-notch packability ensures easy, compact storage between uses.
Goin' Mobile
Ultralight spandex-blend fabric with 4-way stretch combines with articulated knees and a gusseted crotch to keep you quick and nimble all day long.

Weather Protection
Wind-resistant protection and a durable water-repellent (DWR) finish keep you comfortable and dry through chilling gusts and on-and-off showers.

Easy Storage
Roomy side-seam zip pockets and jean-style hand and back pockets offer ample stash space, and the entire pant can be compactly stowed away when not in use thanks to highly packable construction.
