sure seals!!!! Before i had those if i was in the water a lot i would get shorter wear time. Also, if you are using a skin prep, that shortens wear time, sometimes especially with water. I did try the moldable, which is probably what i will switch to when i run out of my hollister bags, and i didn't have problems then either.
The only time i have ever had to change from being in the hottub was after we went to a friend's parents mountain house and their hot tub had WAY too much cholorine, and it actually ate away the plastic!
Other than that, i get about 6-7 days, water time doesnt seem to affect it.
