We put our spin on the classic Corkcicle Tumbler just in time for hot summer gatherings and camping trips. Crafted from stainless steel with proprietary triple insulation, it keeps contents cold and refreshing for 9+ hours and hot for 3. Stays cold even longer with drinks containing ice. Plus, it comes with a sliding, shatterproof, see-through lid. Our signature Mountain Khakis logo is engraved on the side.
