There are too many water bottle carrier production for the Nalgene 1L Bottle, but only few for the smaller Camelbak 750 ml bottle. As a city traveler, not a outdoorer, a water bottle of 1 L is too big and too heavy to carry with. So I design this one.
Inspired by Kifaru Water Bottle Pocket, I designed a smaller bottle carrier specially for Camelbak 750 ml Water Bottle (or any other bottle with a diameter of about 3 in/76 mm or circumference within 239 mm). The main body is almost the same: a barrel with a webbing strap as bottom. It is MALICE compatible and can be attached to MOLLE or belt of any width.
Water bottle is something like wallet that may be accessed frequently. So in my opinion, water bottle carriers with draw cord, flap with zipper or buckle, etc. are all junks, these things only make it harder taking out your bottle. If you really worry about losing your bottle by accident, here is my solution.
With the side webbing, you can even attach a sling to it, and use it as a standalone bottle carrier. In this situation, you can even use the MALICE on the rear as normal MOLLE panel and attach some small pouch to it.
More than Camelbak, this bottle carrier is compatible with many other water bottle brands. Just like I said, this bottle carrier is compatible with any bottle witha diameter within 3 in/75 mm. I studied some popular sport/outdoor water bottle brands and filtered out some compatible bottle production.
