I shower Daily and a year 1/2 ago bought a $60 Shower Guard. Worked great but after the first year or so it was falling apart. So I spent another $60 just to leave it in a hotel a few weeks later. So I decided to try and make my own and it works great. Keeps the Bag almost completely dry. So I thought I would share how I made it. Bought all the stuff from Amazon but you could probably get it at a Craft store.
1" Nylon Webbing (Belt material) Cost for 25 Yards $10 Enough for several belts
1" Quick Release Buckles $3 (Make sure the opening is 1" not the buckel itself.
3ml Plastic sheeting. $14 and can make a lot or be used for other things. You could use a plastic bag but those are usualy less than 1ml thick. The thicker plastic won't cling
So all of the stuff was aboutr $25 and if you bought a larger thing of buckles you could make about 4 of these depending on how big the belt is.
Just cut the webbing a few inched longer than you need it to wrap around you. This allows for weaving through the buckles. Then just put a buckle on each end and adjust for a snug fit.
Cut the plastic the width you need and twice the length, than just fold over the belt.
Now you can shower without worrying about getting it wet!
