After 8 warm-water dives, I found the X2 Xflex 3/2 mm to keep me warm, comfortable and well protected. I noticed no binding or restrictions, whatsoever, while diving. The neoprene is soft and pliable, like a comfortable article of clothing. During the one and a half-hour (lunch) interval between dives, most divers on the boat removed their wetsuits, but I was very comfortable leaving mine on. This also saved me from having to don a wet, cold wetsuit for the afternoon dive. And you just can't beat the price.
