Great bottle for moving around and gym.
I used them a few times prior to the big day as a test. Then ran the UTA50 in these. No blisters whatsoever, warm but not overly hot feet, they wick away moisture fantasticly, can't wit to get a few more pairs!
Fantastic fresh coffee kit you can use anywhere. I have been using this set for the past few weeks on several hiking and fishing trips and its excellent. Grind your beans, boil your water and you have cafe coffee wherever you are. Love it.
