Review on Nalgene Bottle Carrier Handheld: Convenient Gray Holder for 32 Oz Bottles by Ken Kowal

Very nice bottle holder. Keeps my water cool all day. However, I'm not sure what I would put in a zip-lock bag. It's kind of pointless. When inserting the bottle, the secret is to fold the neoprene lip towards the seam. After that, the bottle slides right in. Then turn the neoprene back over. I really appreciate the plastic reinforcement on the hinge. I attach it with a carabiner and put it on my backpack. A big pen is good. It's really well thought out. Addendum: Bought in January 2015. Appearance is not worn. It's hanging from a carabiner and rubbing against my backpack. Everything outside is littered, although that is insignificant. The real problem with this update is that the interior is falling apart. The film inside is cut and peeled off. It didn't wear well. 5 stars to 3. Updated 7/5/2016 - Foil insulator material is absolute rubbish. This is the second one that just falls apart. look elsewhere I'm changing to 1 star.
