Just saw your post. I have the Fusion One. Personally, I love it. The dry suit is much easier to put on, fits more like a wet suit. On my last dive in Feb. Water temp 50 at the surface 44 at 15 and 40 at 22 I was very comfortable used less weight than my dive buddy in his DUI (by almost 10 lbs.) As the DUI hold more air. It took him almost 15 min longer to get into his and I noticed his range of motion was limited compared to mine. The downside to it the outer shell is not meant for use in hazmat situations. The suit should be ordered to fit not sized like other suits that have crotch straps etc to help fit it. As with most drysuits it does require learning the proper way to get it on, but that only takes a few minutes to learn and knowing that makes it a real pleasure to get into and out of. Hope this helps
