The 7mesh Ashlu Merino Long-Sleeve Jersey blends merino wool with nylon, pairing wool's natural thermoregulation and odor resistance with the strength of a non-wool fabric. A full-length front zipper vents heat on demand, and a five-pocket Anything system splits storage across three open rear pockets and two zippered side pockets for gear that needs to stay secure. What Our Gearhead® Experts Are Saying:"7mesh cuts this to an actual riding position, not a standing one, so the sleeves stay put when I reach into the drops instead of pulling back at the shoulder."
