Outdoor Flask Thermos for Unisex Adults

The GSI Outdoors Boulder Flask is the perfect companion for your outdoor adventures. Its copolyester resin construction is designed to withstand any bumps, drops, and dings along the way, ensuring your enjoyment of your "poison" without any foul taste from the flask material.

The wide mouth design makes it easy to fill up or pour directly into a cup, and the attached hinged silicone cap provides a good grip even in cold temperatures, preventing leaks and ensuring you won't lose the cap. Molded graduation marks on the surface allow you to easily check how much beverage remains inside without having to guess.

Weighing only 4 ounces when empty, the Boulder Flask won't weigh you down, even after you fill it. This BPA-free flask is durable, safe to drink from, and offers a fun and novel drinking experience with its see-through design.

Don't leave camp without this handy companion by your side. Celebrate your outdoor adventures with the GSI Outdoors Boulder Flask, and enjoy on-the-trail sippin' with confidence.
