Finally warm!!

I usually go through a wet suit a year, the seams rip, the material wears out, or it just isn’t warm enough. But finally, I bit the bullet for the Kassia suit, and its amazing! I surfed for 3 hours on a cold stormy California December day and didn’t get cold. I lost track of time since my numb hands are my 1hr indicator for my other wetsuits. It doesn’t feel thick and bulky like my rip curl, it’s more flexible than my billabong, and it’s warmer than both. I haven’t had a back zip suit before, always shying away because I thought it would leak more, but this sucker doesn’t leak, anywhere! Plus I’m not tweaking my shoulder pulling it over my head. Win!

BEST EVER

This 4/3 fits true to size and is soft and feels like butter! I can move so well in it and it’s so comfortable. I am warm, toasty and able to surf for hours in it. It’s a MUST buy!
