Great for carrying a 40 oz Klean Kanteen around when commuting via bicycle or other means. Works perfect with a 32 oz nalgene, I bet it was designed for that bottle specifically. It also helps insulate just enough on hot days, didn't expect that because of the dark material. I use it to carry my bike lock sometimes and even a camera lens. Or stuff my gloves into when my pockets are not big enough.. Only reason for 4 stars instead of 5, is I would like to some stronger velcro used, it isn't causing any issues. But I can defiantly appreciate an improvement there.

i occasionally use one to carry a camera lens. I wish there were a couple of bigger sizes available. This product should also be MARKETED to industries that climb towers, or other high structures where people working need to have a safe way to carry a bottle of water with them while working at great heights above the ground.

Tried a number of water bottle holders on my pack belt - nothing worked particularly well. I use this holder with a 500 ml Nalgene; compact; light and not noticed during long hikes- easily accessed. Great product
