Review on Leverage Convenience with the Clakit Small Pocket and Small Water Bottle StrapPack Bundle - The Ultimate Backpack Attachment for Hikers, Travelers, Commuters, and Students by Michael Colley

This is a smart and potentially useful system, but I found both the pocket and water bottle holder to be too small for my needs. I returned them. The clip is strong, holds well and provides a secure mount for the various devices this system is designed for, but I would recommend the large pouches and bottle holders, particularly for those considering using this system to store a small zoom lens I was. Instant access to a second lens is what many photographers need, especially those of us who shoot a lot of photos while hiking. But even if you are using it to hold a water bottle, go for the larger size as the amount of water in the bottle held by this item would be too small to be of much use. Great idea but the dimensions are too small to be useful for those walking or cycling and there are better alternatives.
