With the shape of the sitting driver in mind, Sparco's K-33 Ergo-7 Kart Racing Suit borrows Ergo technology from Sparco's racing line. Designed for maximum comfort and performance while in a seated position, the Ergo-7 has no front zipper. This not only creates an excellent template for sponsors, but also reduces torso bunching while seated. By integrating the zippers into the shoulders of the suit, getting in and out of the suit is a breeze. Stretch panels run the length of the suit to not only help in putting-on/taking-off the suit, but also in overall driver comfort and performance. Air vents are positioned on the upper chest, internal thigh and arms, while the inner lining is extremely breathable during hotter races.
