Available in any colour variation to suit your personal style.
This will (as you can see in the second picture) hold up to a three litre bottle securely. The belt fitting is brass and the clip is aluminium.
There's not much more I can say about it other than if you prefer your bottle to be quicker access than inside a pack or bag, give this a try.
*Note, will not fit wider screw top bottles* Neck width is fixed
Alu clip colour
