Needed - -Water bottle holster/with kung fu grip

I need a water bottle holder that will hang on to my bottle. I like to use a one liter bottle. Sucking on a tube aint my thang. I have a Catalyst and tried the ULA water bottle dropper method in different configurations with different bottles. It adds mileage to my days to chase my water bottle down every gully I pass and in an effort to be more efficient I would like to hang my bottle securely. I saw a pic of Bearpaw using one - I will send him an email asking where he got it.

I like having the bottle hanging on my shoulder strap - it seems to be out of the way there. Effort vs cost might dictate purchase vs myog in this case.

Any ideas?

I use 20 oz. Gatorade bottles for the shockcord and cordlock bottle holders, however they will fall off when full. I never carry more than a pint of water in the bottle and that solves the problem.

A heavy duty rubber band around the neck of the bottle with a carabiner would work.

This is a commercial bottle holder.

The bot spot from simblissity looks good, but price is too high.
