    Perfect Fit

    Bought these as a replacement for something I already had, just needed the slightest bit more fluid capacity. 20 oz is the ideal size, and I love the wide-mouth opening for filling it with powders. Bought (2), so I had enough for a race without having to carry a large bladder. Awesome soft flask!

    Pretty Awesome

    I've never used an ultraflask before, but purchased two to go with a new OM Gear Vest Pro. Things I love: 1) they collapse as I drink from them, which really minimizes the amount of air coming through the line; 2) they never leave the vest, so I don't have waste time/thought/energy fumbling with them; and 3) they're extremely light weight. One reviewer said the nozzles hit them in the face, but that's easily fixed by tucking the nozzle into the loop on the shoulder strap of the gear vest. Problem solved. The ultraflask is just a really well-designed product. I use Maurten drink mix for my hydration/fuel, and I especially appreciate that the ultraflask is meant to hold 500 mL. It would be great if OM could print a 500 mL fill line on the ultraflask, but I'm smart enough to work around that.
