The pocket shower zips into a 3" x 6" pouch and only weighs 4.25 ounces - super handy and convenient.
Reviewers report a very weak flow from the nozzle when used.
You can get about an 8 minute shower from the pocket shower when you have the shower head open on full. Adjust the pressure by twisting the shower head. The best part of this shower is that you don't have to use it as a shower all the time. You can also use it as a sack to carry your dirty clothes in when you're heading back home.
