Bring the GSI Boulder Flask on Your Next Adventure
 

The coolest feature of the ultralight Boulder Flask from GSI is that it’s see-through, allowing you to monitor your consumption & make sure it’s always full. Its clear, co-polyester construction is lightweight and eco-friendly as well as shatterproof. The bumper around the edge gives you a good grip while you tip back 10-ounces of your favorite adventure juice.
