Awesome design for shoulder strap and molle attachment, no longer required external water pocket for backpack
Love this new base. I was able to add the 450ml bottle to my waist pack easily. Now I can have a little more water on my MTB rides.
Bought this so I could add an additional water bottle to a hip pack. My bike can only use the small fidlock bottle which for me lasts 30 minutes. This clips over the Ergon hip pack and I can carry an additional 20 oz for a longer ride. For All day rides I would use a hydration pack and if I needed to I could add a bottle to the shoulder straps. Great piece of kit.
