If the LL Bean swimsuits are anything like their backpacks, they will also hold up. Have had two LL Bean Backpacks. Got one in middle school, had it until the end of high school when we donated it and I got my one for college, which has gone with me to WDW (My friend and I abandoned our purses in the room and put our stuff in the backpack, then alternated who carried it, so it's been to every park and on most of the rides) and Hawaii, plus to school obviously, and you cannot tell that that backpack has been everywhere. My old one was in such good condition that we donated it. I really just needed something slightly bigger with a laptop sleeve for college. Love their backpacks.
