Water temp is 76 and I am diving at 26 feet. Pretty easy to get on, I wasn't sure it was going to be for me. I have tried a few of these on and this one is one of the better fitting ones.
I am 43 and have been diving for about 5 years, I started exploring cooler waters and noticed I was tired pretty quickly and running out of air. I asked the dive master why and he suggesting maybe my body was over working to stay warm. I now wear a hood, boots and gloves. I have seen an improvement in my overall body temperature. I don't feel as fatigue. The hood was easy to get use to, I am a large based on the sizing system. Happy with my purchase.
