What Our Gearhead® Experts Are Saying: "This baselayer is my go-to for cold-weather intervals and long, windy ski tours. The windproof front makes a big difference, especially when descending. It breathes incredibly well and the snug fit doesn’t restrict movement. I also love that it's made from recycled materials—performance with a purpose." We don’t slow down when the wind picks up—we layer smarter. The Craft Active Extreme X Wind Long-Sleeve Baselayer delivers the tech and protection we need to train hard in cold, gusty conditions. Built with SEAQUAL eco-friendly polyester and Coolmax Air Technology, this high-performance piece regulates our body temperature and wicks moisture when we’re pushing hard, all while minimizing environmental impact. The two-layer windproof panels across the front, shoulders, and sleeves help shield our core when the elements get harsh, without sacrificing stretch or breathability. Flatlock seams reduce friction, the waffle-knit design enhances airflow, and the tight fit moves with us through every stride, push, or pole plant. Whether we’re chasing personal bests or braving morning runs, this baselayer keeps us warm, dry, and focused.
