Exceeds expectations!

So I have only 2 suits to compare with. First is a Pearl Izumi Elite, and this one. I feel like the th Pi is good enough for sprint or possibly Olympic? But by far and away this ultra will be my primary suit. The materials, construction, and a pad are at a whole different level. I highly recommend this suit. One reviewer on amazon said sleeves a n legs were tight. Apparently they didn’t follow sizing chart. As a swimmer, my shoulders arms and back are definitely on the larger size, this fits perfectly with great flexibility. Best gear purchase yet!

Excellent material

The size is perfect and is very confortable, so far I have used it only for training and I am very happy due to the fact that I have not feel any overheat.


Just finished an IM 70.3 in this kit and it was very comfortable at all stages of the race! It fits true to size and i did not overheat at all on a very hot day... My only complaint would be that there is only 1 small back pocket dead in the middle of your lower back which is a bit difficult to reach for nutrition and kind of limited in capacity. I still give this 5 stars despite the back pocket.

Sleeveless kit!

Was happy to see my son loves this (sleeved) skin suit! He is autistic and certainly can be picky. He is nearly 5’11 and barely 140lbs so the medium worked well! I will need to look at the sleeveless.... my shoulders are quite a bit broader! Great suit!

Performance and comfort!

Love this short sleeve aero racesuit! The first time I wore it was during a 6 hour training ride and I had no issues or discomfort. Very breathable and no issues with the zipper rubbing my skin. Highly recommend!
