Get ready to take on any conditions with the Sitka Jetstream Jacket.

this is sitka's description of this great jacket:

It may sound contradictory, but this soft mid-layer is built for punishing granite-tough terrain.  Sit back against a rock ledge totally shielded from the wind and confident the strategic seam lines are directing the water away from you.  This jacket features the Gore-Tex Infinium Windstopper membrane, DWR finish, micro-check fleece backer, drop away hood, pit-zips, forearm pockets and an athletic fit.
