Description of Norrøna Trollveggen Dri3 Jacket - Men's:
Pull on the Norrøna Men’s Trollveggen Dri3 Jacket and get lightweight protection that holds up to the rigors of alpine climbing. A Dri3 waterproof breathable membrane and waterproof zippers keep moisture out, and an adjustable storm hood and hem drawcord seal out blowing snow and cold wind. Norrøna put four-way stretch panels on the shoulders, arms, and back so you can reach for that next ice tool placement without the jacket riding up.

Bottom Line: Durable protection for harsh alpine environments.
This fits exactly as stated. I've worn it during several rides, all when it was raining very heavy. The weather ranged from 40's to the 60's. In all cases, I was completely comfortable and totally dry (at least from waist up) at the end of the 2-hour ride. I've had other jackets, and they couldn't do all this, plus they usually were really bad for cycling.
