Best For: Mid-Weight Base Layer

Boosted by XLANCE®, the all-new Vital S2 is our most comfortable mid-weight synthetic base layer bottom to date. With a lightweight 140 g/m² fabric, it delivers a soft next-to-skin feel and exceptional moisture-wicking and quick-drying performance—ideal for cold conditions and high-output ascents. Its minimalistic design also makes it perfect for sleeping in and for bridging the gap on colder days when the Attack Pant isn’t quite warm enough, yet the soft-shell Guide PRO Pant feels too warm. It’s ideally worn on hunts when the zip-off feature found in our other base-layer bottoms is not needed.

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.
