Summit Wasserflasche mit Strohhalmdeckel

Took this on a long hike and the water stayed ice-cold for nearly five hours, which shocked me. The straw lid locks tight enough that I tossed it in my bag without a single leak. This is the bottle I've been looking for.

The vacuum insulation actually keeps my water cold for several hours during my hikes, which is a big plus. My only small gripe is the straw requires a bit of a suck to get the flow started, but it’s still a solid bottle.

I like that the straw lid stays closed securely in my bag without leaking, even when I toss it in sideways. The vacuum insulation keeps my water cold through a full workday, which is exactly what I needed. Only small nitpick is the straw feels a bit stiff at first, but it softened up after a few use
