UltraFlask™ Speed 500ml

I was skeptical about soft flasks bouncing around in my vest, but the wider form fits so snugly in the pocket that I forget it's even there. The pliable material makes it easy to squeeze out every last drop, and the 3D welded bottom keeps it standing upright on the trail when I set it down for a sec

The 3D welded bottom is the first thing I noticed—it actually stays upright on my desk while I’m refilling, which is rare for a soft flask. The wider shape fits snugly in my vest pocket without sloshing around, and the pliable material makes it easy to squeeze every last drop.

Finally a soft flask that stands up on its own while I fill it. The pliable material slides into my vest pocket without any wrestling, and the wider shape keeps it stable even when I'm moving fast.
