YETI and Hydroflask are around the $40 mark, and there’s not much between them for quality. Both bottles are well insulated and keep contents cold longer than most competitors. Chuggers may find the YETI design to be the ideal water bottle choice because the chug cap on the classic Rambler spins off with ease thanks to the handle at the top. Hydroflask’s Flex Straw Cap is a great design, too, and will suit people who prefer to sip through a straw.
