Hydro Flask 40 Oz Lightweight Trail Series Wide Mouth Flex Cap Quartz Bottle

Hydro Flask 40 Oz Lightweight Trail Series Wide Mouth with Flex Cap Quartz

Built to go wherever the day takes you, the 40 oz Trail Series bottle meets the demands of long days on trail and in town. The all-stainless-steel design delivers the cold refreshment Hydro Flask is known for, but it feels noticeably lighter—about 20% lighter than other 40 oz Wide Mouth options—so you can carry more water with less bulk.

The bottle features TempShield double-wall vacuum insulation, helping maintain beverage temperature and reduce condensation. It can keep drinks cold for up to 24 hours and hot for up to 12 hours, depending on the environment and usage. The wide mouth makes loading ice, water, or snacks easier, and the Flex Cap quartz lid provides a secure seal for on-the-go movement.
