Review on UltrAspire x UltraFlask 550: Advanced Green Water Bottle for Optimal Hydration by Trevor Garrett

I have been running long distances for almost 30 years and have tried many different hydration systems during that time. Ultraspire's Speedgoat belt bag is actually one of the best two-bottle belts I've tried, but the bottles themselves are terrible. They literally lick every time they are more than half full. Even brand new ones, and since I usually carry something with electrolytes on me, I'm constantly plagued with sticky liquid running down the backs of my legs. Unfortunately, the fanny pack itself is designed for its specific bottle, so I can't even switch to a different bottle.
