All Hydro Flask products are made with 18/8 pro-grade stainless steel, and designed to be the lightest weight and slimmest profile insulated bottles on the market.  They will keep your beverage of choice ice cold for 24 hours or piping hot for 6 hours, and you get no condensation on the outside of your bottle.

NEW - this standard mouth bottle can be used one-handed! Flip the Flex Straw Lid up to drink. When closed the Flex Straw Lid is leakproof, so you don't need to worry about getting the inside of your pack wet.
