So I ordered some trest recently and just got done wearing one and I still think I had room to go! Last night I got strapped into one around 9, locking mits and the key was frozen. First off the outer plastic is way softer than rearz, they fit similam and knees touching is not gonna happen. Fast forward, I woke up had to go then waited for the keys to thaw drinking pre poured sippies and bottles. FINALLY the keys thawed after another wetting or 2 and I wanted to go to the gas station get myself a few beers then come home and game. Not once did I leak but definitely felt moisture spreading around towards the back. These have to be my favorite longevity wear ever. If you've been on the fence because of price I get it, but don't rob yourself of such a poofy experience! Might double up with an aquanaut tomorrow and I'm pretty sure the waddle game with be strong with this bb boi!
