Engineered for Unrestricted Movement & All-Day Freshness
Discover the ultimate upgrade to your adventure wardrobe with our rebuilt men’s base layer. Designed around the male form, it eliminates chafing through strategic flat seams and a contoured fly/seat construction—perfect for hiking thermal underwear or intense outdoor sessions.
Why Adventurers Trust This Cold Weather Base Layer:
Smart Fabric Science: Inside, 100% ColdPruf® polyester wicks sweat rapidly while SILVADUR™ actively fights odors. Outside, a rugged 70% polyester/30% merino wool blend balances insulation and breathability at 7 oz. weight—ideal for variable climates.
Comfort Engineered In: Hidden seam cuffs prevent irritation under gear. The non-binding waistband and extended front/back rise move with you during climbs, cycles, or commutes—no tugging or bunching!
Whether scaling trails or braving urban winters, this non-chafing long underwear adapts seamlessly. The moisture-wicking core keeps you dry during sudden temperature shifts, while merino’s natural temperature regulation ensures consistent comfort from dawn patrols to après-adventure downtime.
Key Upgrades for Modern Demands:
✓ Anatomically tailored seat/fly
✓ Abrasion-resistant yet soft cuffs
✓ No-slip waistband with flex zones
✓ Reduced bulk under outer layers
Reimagine resilience—layer up without compromise.
