Phil's Thoughts: Better than expected. There's a good thermo lining on the inside from the chest to the knees and the same on the back side, Good flexibility as well. Since it's only GBS seams, you're probably not going to be having 4 hour sessions in this suit. And remember Billabong is a way different fit than O'Neill or Rip Curl, so it's best to try one on to make sure you're getting a good fit.
