Vital PRO Hybrid Insulated Bottom | Ash

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.
