As the temperatures drop and the trails turn from “hero dirt” to all out mud-fest to frosted crust, the kit you’ve been riding all summer simply makes less and less sense. For fall mountain biking, you need a more rugged and calculated setup to stay comfortable and perform at your best. Gone are the ventilation holes and mesh panels. Fall mountain bike gear is all about wind-stopping materials, merino wool and a degree of insulation. While your down jacket or fleece may keep you warm, it lacks the breathability needed on heart-pounding climbs. These pieces will keep you riding at your peak as fall steps into full force and winter creeps in around the corner.
Base Layer
The base layer is the most important part of your kit. Without a good base, the rest of your layers won’t perform the way they should. In this sector, merino wool is a top-performing favorite — its natural insulating properties, unmatched breathability and inherent antibacterial qualities make it a no-brainer while out on the trail. These insulating tights also feature a built-in chamois, which eliminates the need for bibs. For those who are still anti-wool, synthetic materials offer a much lower price point, but with a performance penalty.

Upper Body
For the upper body, a good jersey over a base layer will keep you plenty warm and will offer the breathability needed on long climbs. Fall rain showers are common especially at higher elevations and having a lightweight, packable wind and waterproof rain shell to layer over your jersey is essential. While your standard waterproof rain jacket will do most times, when you don’t need it you’ll be carrying excess weight.
