  • Excellent wet suit, fit perfect, lots of buoyancy
Size: L1 (195-220 lbs) Style: Black/Blue
Bought this for my first Olympic triathlon and I have nothing but positive things to say. I'm 6' 2" 195lbs, lean body with normal leg / torso ratios for my height. I got the L1 and it fits perfectly. Do yourself a favor and watch the GTN YouTube video for donning a wetsuit. It makes all the difference particularly for swimming range of motion. For range of motion (ROM) this is my first wetsuit so I don't have much of a comparison but I felt a very slight decrease in arm ROM and a moderate amount in knee bending. This all seems normal to me and is improved by pulling extra fabric into around the shoulders & armpits. Overall, I think the ROM is quite good and any issues are offset by the buoyancy. The buoyancy is a game changer though. This is particularly true for your legs. I didn't have any of the leg sinking I've come to associate with sighting in the pool. It really improves your experience and you expend less energy. Overall, the fit was perfect, the material and zipper feel quality, and the buoyancy is a game changer. Highly recommend. I can't imagine what those $1000 wetsuits are really improving enough to justify their price. ... show more

  • No fuzz. All very good.

The rarely found no-feel wet suit. No flaws. Just ordered their high end Hybrid, wondering how it can be better than my Endorphine (second model in line of four)

  • $300 for a leaky wetsuit.
Size: M2 (165-185 lbs) Style: Black/Blue
What an incredible waste of $300. In 30 years of wearing wetsuits for surfing and open water swimming I've never been so so amazed that a brand new wetsuit would leak water through the zipper as this one did. Within the first minute the wetsuit was completely sloshed with water. What's amazing is that when I put the suit on, it had an amazing tight fit and was very flexible. I even got out of the water, rezipped and fastened the velcro again, to the point where it was super tight around my neck. I just don't understand how there is this much water coming in through the zipper and back. ... show more

  • Excellent but......
Size: L1 (195-220 lbs) Style: Black/Blue
I've had this wetsuit for two years. I rotate it with my Zoot Kona and I go around 4x per week. The pro is that it has better range of motion than my Kona suits and is easier to put on and take off. The con is the neck has come apart after about a year. I took it to a wetsuit repair shop and was a cheap fix. The fix area and the rest of the neck is starting to disintegrate all over. I like this suit for events because it is least restrictive, but not as good overall quality as my Zoot wetsuits at around the same price point. I want to buy another one, but they raised the price and rarely go on sale in sizes bigger than XS and M. I'm an L2. If they drop the price back down a bit I'll consider replacing it. The coldest I've swam with it was 52º F and was comfortable. I guess I can't complain after two years of regular use, but read a few reviews about the neck disintegrating. ... show more

They delivered a great wetsuit for a fair price. I use it several times a month as I train in open water.
