Good, not great fit

Preface that haven't trained or raced in the kit yet. Purchased due to loving Zoot's products and wanting to move to a 1 piece. Have always been concerned by potential fit associated with my high side of healthy BMI. This said, kit overall fit well, with the exception of the arms, which are quite snug around the pits. Note that my arms aren't tiny, though definitely no where near a body builder either. Considered returning but decided to give it a longer trial.

Great aero fit, COOL

Got this kit because I needed something to help me stay cool predominately. Secondarily I wanted a more aero cut. The minute I put it on I could feel the cooking affect just walking around. It was pretty amazing. Haven’t gotten to race test it yet, but I took it for a 58 mile ride and then an hour run and it is super comfortable - no chafing or ride up, and helped keep me cool in the heat. In direct sun I could feel a little more sun from the color, but in terms of evaporation and skin cooling it was great. Looks amazing, and def provides a boost of confidence going into race day.

Nicely Done Zoot

Quality suit. Well made. I am 5’7”, 155lbs, and fairly broad chested. The Medium fits snug in the chest, but at the same time did not restrict my breathing during swims. No chafing during biking or running. Huge improvement over my entry level (cheap) TYR. I’ll be back for more Zoot products.

Great Kit.

Well made, form fitting kit. Very happy with it and will be racing a 70.3 in it this weekend.


Perfect fit, dry and super comfortable! Love it
