Best Use: Frigid Conditions, Low-Level Activity
Built for the coldest conditions when a typical thermal bottom just won’t cut it, Vital PRO answers with body-mapped insulation for targeted warmth strategically paired with single-layer paneling for added breathability. Vital PRO’s hybrid construction is built from a 4-way stretch blended polyester with a peached soft-touch finish. Housed between two layers of material, the insulated sections leverage a layer of 80-gram synthetic insulation with high-stretch and rapid-recovery qualities for non-binding articulation.
This ultra-warm, insulated thermal bottom keeps warmth close to your core, wicks moisture, dries quickly, and remains odor-free for all-day performance. The added insulation also creates a thermal break from frozen ground while seated. Whether you’re hunting big game, whitetail, or waterfowl, the Vital PRO base layer system is ideal for freezing temperatures with low activity levels.
92% Polyester / 8% Spandex single knit jersey – 172 g/m²
100% Polyester high-stretch insulation – 80 g
Anti-odor treatment
This insulated base-layer bottom is sized with an athletic next-to-skin fit to layer over a brief and under a hunting pant. Only upsize if you measure between sizes.
