Pearl Izumi Summit Shell Jacket

When you're headed to the summit, expect to encounter a whole host of conditions. The Pearl Izumi Summit Shell Jacket isn't messing around, it's a mountain bike-specific polyester shield that packs small and weighs only 110g, so there's hardly a reason to not take it along with you. Treated with an eco-friendly DWR to fight water and trail spray, this is a wearable mudflap from one of biking's classic brands.
