This new SIDE POCKET ECHO is an infinitely-adjustable insulated water bottle pocket. It will securely hold anything from a small 0.5 liter size, up to a huge 1.5 liter size. The pocket can be adjusted to exactly the size of any container in that range. Maximum Bottle Diameter is 3.75 inches (95mm).

The SIDE POCKET ECHO takes the form of a neoprene sleeve that wraps around the water bottle and it secures with two clips on two straps. It makes for a perfect fit, regardless of the the size of the bottle, and it allows one-hand removal and replacement of the bottle.
