Vital S3 Zip-Off Bottom | Ash

Best For: Mid-Weight Fleece Base Layer Boosted by XLANCE®, the all-new Vital S3 is our most advanced fleece base layer to date. Drawing inspiration from the legendary Peloton 97, the Vital S3 delivers upgraded advantages with an improved fit and a more advanced fabric.The full-length leg zippers and above the boot design allow you to easily add or shed layers in changing weather conditions without removing your boots and outer layer pant. Its ultra-soft brushed fleece interior provides a comfortable next-to-skin feel with exceptional moisture-wicking and quick-drying performance. It keeps you dry and comfortable whether you’re locked in glassing for hours or pushing hard to the next ridge — especially in cold to frigid conditions where a standard base layer falls short. 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.
