Yukon Outfitter's Freedom Tumblers offer superior temperature retention and lasting performance. Constructed from high-grade 18/8 stainless steel, these double-wall vacuum insulated tumblers keep drinks hot for up to 6 hours and cold for up to 24 hours. Copper plate insulation, a UV tint slider lid, and a sweat-free exterior enhance functionality. The DuraGrip powder coat finish provides an ultra-durable, textured grip (excluding the stainless steel variant). Freedom Tumblers are BPA-free and designed to fit most cup holders.
