Boulder Flask

The kids might get some dehydrated desserts on the backpacking trip, but the GSI Outdoors Boulder Flask is a dessert specially reserved for parents and other responsible adults. GSI Outdoors made it lighter than standard flasks, and it's still exceptionally durable for the outdoors. It has a good grip, and the attached cap can't get lost.

No metal. Good sneaky flask.

I bought this flask for backpacking. I like it. It's lightweight and holds quite a bit of liquor, actually. More than any other flask I have, which makes it perfect for a weekend trip. BONUS! It is also completely plastic and silicone, which means metal detectors won't find it at pricey concerts (as long as you hide it well).
