Ive swum in it a lot of times

Ive used it in swimming pools, water parks, in the ocean...and even used it while water tubing

The swimming binder is about 3-4 months old in that photo which I just took today!
When I go in swimming pools, and my body is underwater, the rash guard seems to loosen up and hang over you in a way, so its not really noticeable. Its when I first get out of the water, the rash guard seems to cling to the binder...thats the only part I hate

I have to pull on the rash guard a little to get it away from my body again and get it back to that looseness rather than tightness! I reckon that if you hardly need a normal binder usually, then it could possibly work for you too
