Works great in the MTB bottle cage for short rides when I don’t want a pack. Stays cold for quite a while with a few ice cubes added. The valve allows for fast enough flow to get a reasonable amount of fluid quickly.
Wish the neck slimmed about 1/3 down like my Camelback, to help it hold more secure in a typical bike water bottle holder. I like the spout, but it should have something like a plastic dome cap to prevent dirt from collecting in it.
