Comments: I used this bottle during my most recent 100 Mile race, and I was very happy with how comfortable it was during the entire 15+ hours that I carried it. I do need to mention that I changed the bottle to one of my older Nathan 20 oz bottles, because I like the feel of the softer material, and I'm not a big fan of the indents in the UD bottles. I also prefer a traditional valve. The strap on this bottle is surprisingly comfortable given that it looks pretty narrow. It's great for use in races, and I've never really felt the need for a pouch in my water bottle carrier, so this was just perfect.

Comments: I have used Nathan, Amphipod, and now the UD Jurek Grip. The Grip is by far the best handheld I have used. Very minimal, as it is described, and carries easily in the hand. I never feel like I am squeezing the bottle while running. Drinking from the Kicker Valve takes some getting used to but it's not as bad as some make it out to be.
