The Power Bike Short gets its name from the high elastane content of the special fabric we've sourced from Italy. It has more compression than our other bike shorts and is slightly longer so it supports the entire hamstring and quadricep muscles. Along with a UPF 50+ rating, it also has a wide v-front waistband designed to provide extra core support. The fit is tighter but the result is enhanced support and reduced muscle fatigue. The Power Short is also outfitted with a deep pocket on the right leg and the latest in soft, laser-cut leg bands that hold securely without digging or pinching. It comes with Terry's best Flex Air Chamois with soft wing construction for the ideal balance of padding, ventilation and low bulk. Proudly designed and sewn in the USA at a green energy-certified facility, supporting local jobs and the highest standards in quality and fit.
