"What Our Gearhead® Experts Are Saying:""I use the Endurance 4 Short when I want the same performance as my favorite bibs but without the straps. The Progetto X2 chamois is still unbeatable for long mileage, and I love the compressive feel of the fabric—it supports my legs without feeling restrictive. It’s ideal for warm days or indoor sessions where bibs can feel like too much.""We reach for the Endurance 4 Short when we want pro-level comfort and performance without the added coverage of bibs. Built by Castelli, these shorts use Endurance Evolution fabric to keep muscles supported and sweat under control, even when the miles stack up and the temps rise. The Progetto X2 Air Seamless chamois is what makes the difference on long rides—dual-layer cushioning and seamless construction eliminate discomfort and keep airflow high. A supportive waistband replaces the bib straps, and GIRO3 leg grippers keep the cuffs comfortably in place. Whether it’s hot outside, or we’re logging big indoor training hours, these shorts check every box."
