  • Excellent wet suit, fit perfect, lots of buoyancy
Size: L1 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

  • Marginal quality, flexible, open water wet suit..
Size: S2 Style: Black/Blue
Buyer beware! The supposed 2 year warranty on this wetsuit is complete and utter nonsense. It is supposed to be a 2-year warranty but after 3 months of use, the collar started fraying and peeling and separating from the rest of the wetsuit. I sent in a full warranty request claim to synergy and they came back telling me it is not a defect. I'm very careful with the wetsuit, never dry it in the sun, always store it flat on the floor, never leave it in a hot vehicle, rinse it in wetsuit cleaner every few swims and it still fell apart and is garbage! Do not be lured into a false sense of security with their non-functioning warranty and do not waste $340 on this wetsuit! ... show more

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

  • No fuzz. All very good.
Size: L1 Style: Black/Blue
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)

  • Terrible smell Not recommend to persons with a sensitive skin
Size: L3 Style: Black/Blue
The wetsuit is good, but it has a bad smell. I have a skin etching when wearing this suit. I washed it in a warm soap water, but no effect. How to remove this . Thanks
