Osprey Packs: Stratos 18 Backpack

When the nor'easter is not at your back, this wind-blocking soft shell keeps your spirits up. Our warmest soft shell is made with a breathable, lightweight polyester and spandex fabric and has a Deluge® DWR (durable water repellent) finish to protect against snow and light rain; heavier windproof panels on the front torso and undersides of the arms are bonded to a stretch-woven fabric and a warm, wicking grid-patterned fleece back to keep cold wind out. Details: top-stitched seams for durability; collar lining is brushed for warmth and moisture-wicking performance; a center-front zipper with a wind flap to keep the chill out; stretchy underarm gussets and articulated elbows for freedom of movement; cuffs have external zippers and wrist gaiters for a tight fit around gloves; a drop-tail hem that tightens up with a single-pull drawcord to seal out drafts. With one zippered chest pocket and two zippered handwarmers.
