Hydrapak Stow Bottle 1L - Malibu Blue - HYD-00976

When you're used to Nalgene bottles etc., you think you know what a liter looks like -- but this turns that on its head. It's very compact and fits nicely in my ski backpack (too big for my pocket comfortably but ymmv). The flexibility means it doesn't cause pain or that feeling of being pushed off against the chairlift back that I get with traditional bottles. The cap is a bit tough to get on but has been very reliable -- no leaks!

This little gem is so easy to carry along on a hike, walk, snow shoe or ski. I like that when it's empty into the pocket it goes. Also a fine water vessel to bring on the airplane. It's harder to fill at water bottle stations.
