The SMMT Lab x XTRATUF Vol. 2 Serpa 26oz Bottle is a limited-edition collaboration featuring Field Camo artwork by Tyler Poyant, rooted in a 1950s duck camo pattern that echoes the decade XTRATUF crafted its first boots. Built from BPA-free, kitchen-grade stainless steel with El3vate Thermal Protection, it keeps cold drinks cold and seals completely with the Sip+Stow lid system featuring a magnetic stow mechanism. The included Serpa high-flow chug lid is compatible with any Serpa vessel, and a knurled-grip silicone carry strap adds functional convenience in the field or on deck.
