What Our Gearhead(R) Experts Are Saying:"I wear the GOREWEAR Base Layer Brief under my bibs on any ride over two hours and it has genuinely changed how I feel in the back half of long efforts. The polypropylene fabric moves moisture away faster than anything else I've tried at this layer, and the flatlock seams stay completely smooth against the skin no matter how many miles I put in."The best kit is the kit you stop thinking about the moment you clip in. The GOREWEAR Base Layer Brief is designed with exactly that goal in mind, sitting next to the skin and quietly handling moisture management so nothing else gets in the way of the ride. GOREWEAR built this brief for cyclists who know that comfort over distance is a system, and that system starts here. At just 1. 2 ounces, the polypropylene and elastane blend is thin enough to layer seamlessly under a chamois without adding bulk, and efficient enough to keep moisture moving away from the skin throughout the full effort. The brushed elastic waistband transitions cleanly against the hip, and the flatlock seams are positioned and constructed to sit completely flush so there is nothing to create friction over the course of a long ride.
