The EQUIPE Spring Fall Skin Layer P1 rebuilds ASSOS's base layer platform around a new Dryarn material, improving breathability, moisture management, and odor control over the standard Spring/Fall Skin Layer. A Circular Seamless knit runs thicker across the chest, shoulders, and sleeves for targeted insulation, then thins out at the stomach and back where wind exposure matters less. The single-piece construction eliminates seams that would otherwise chafe under a jersey during a long, cool-weather ride. What Our Gearhead(R) Experts Are Saying:"I could feel the chest holding heat on a cold descent while my back stayed dry from the climb before it, no clamminess waiting at the bottom. That's zoned insulation actually doing its job, not just a marketing term."
