    Best

    The best foam I have ever had! It's incredibly warm and tight, while also being very comfortable. The downside is that it was a bit tight at first and the glued seams sometimes hurt, but this is standard with this type of wetsuit.
    I always recommend taking a bit too small rather than too big, as the foam will stretch after a few uses - it is very flexible. It is also very tight.
