Vital S1 Short Sleeve Crew | Black

Best For: Ultralight Base Layer

Boosted by XLANCE®, the all-new Vital S1 is our lightest and most comfortable synthetic base layer to date. With an ultralight 105 g/m² fabric weight and a mesh matrix for high breathability, it offers a silky next-to-skin feel with exceptional moisture-wicking and quick-drying performance—perfect for high-output ascents followed by extended glassing sessions and the unpredictable temperature swings of mountain hunting.

XLANCE brings entirely new performance to hunting apparel: an advanced polyolefin-based stretch yarn with built-in resistance to sweat, chemicals, heat, ozone, and UVA/UVB radiation. This delivers long-lasting elasticity and garment durability while staying incredibly light. It overcomes the typical pitfalls of spandex and elastane —excess weight, bacterial odor retention, slow drying, and loss of shape over time.

Unlike the aggressive snap-back of traditional elastane, XLANCE provides gentle, low-force stretch that’s noticeably more comfortable and fatigue-free during dynamic movement, yet it maintains excellent recovery for season-after-season reliability.
