CO2 Tank 20 Oz Bottle Straight Jacket W/Belt Clip from Power Tank. Here's another way to carry a 20 oz. bottle beside the holster. The 20 oz. Straight Jacket is a simple wrap-around sleeve that clips the bottle to your belt or pocket.
It is made of Ballistic nylon with a sure grip material on the inside to keep the bottle from slipping out.

Nylon webbing and metal D-rings cinch the sleeve around the bottles tightly. Use this item as your main bottle carrying system or use it to hold spare bottles when climbing ladders.
