Leading the way in aerodynamic advancements, the NEW ZOOT ULTRA AERO SS RACESUIT uses a revolutionary new wind-cheating 3D textile.  AERO fabric is wind tunnel tested to reduce drag and make you faster.

AERO fabric incorporates technology and research from the surface of a golf ball.  The dimple structure of the AERO fabric is placed in critical areas of the garment to reduce the vortex of air, which is generated behind the athlete and, consequently, reduces drag and saves watts.

    Look Fast

    Feeling like I'm going to have to train harder for my races so I can actually be as fast as I look in this suit. Great material, flattering, feels great, thicker shammy for those longer races.I am 5'5 155, curvy, and it fits well. Was nervous because my bust and waist met the medium measurements, but my hips are 2" bigger than the measurements. I wore a large last season and felt it was too bit at the top, feeling good in the medium. (Have not actually worn it in a race yet)

    Great kit!

    I am really happy with this purchase. Did a 70.3 in it recently and it wore well under a wetsuit, dried fast, and kept me cool. Extra bonus, I had zero chafing. The size medium fit perfectly and I am about 5’5”, 137 pounds, athletic build. Highly recommend.

    Perfect for IM

    This Zoot Ultra Kit was perfect from start to finish in the heat of IM Cozumel. The sleeves stayed in place during the non wetsuit swim. The material had a great cooling effect during both the bike and run. The legs provided perfect compression. No chafing 🙌🏻

    Great Tri suit

    The suit was great for
    The swim. Very slick in the water. Super comfy on the bike and the compression in the glutes/hips especially made the run so much better!! Plus, super stylish!!

    Great fit and style

    excited to start race season in this kit. feels fantastic
