Proud to represent Team Mach!

One proud ambassador, I loved every bit of what this kit has to offer. Finishing my first race in a Mach tri-suit in 70.3 Texas, I can say that I am extremely satisfied and happy to share this product to my network! I will be purchasing more!

Cool Design

The Fabric seems comfortable and smooth. I can't wait to wear it for New Jersey State Olympic Triathlon next month..


Fits like 2nd skin! Looks great and feels great. High quality product.

Morgan Stebbins
So comfy and good looking!

This is really a great tri-suit. Comfy and compressing and looks awesome. My only quibbles are that I personally don’t like a waist band and I just can’t get used to the feeling of fabric over my arms when I swim. Having said that - I also really like how it feels on!

Felt like I was flying

Where to even start! It's fantastic to run and bike in. Feels like a second skin. Hugs the body in all the right places, not to mention their designs are current and stylish. Definitely going to be my go to tri suit for years to come.
