Description of Mountain Hardwear Transition Jacket The perfect cool weather, active gear: windproof, breathable and lightweight with inset stretch panels and a DWR finish. Wear alone or over a lightweight baselayer for aerobic activities. Sheds light rain and snow. "The Transition Jacket is my choice for active wear when I need less insulation and something to cut the wind without giving up breathability. The light material flexes and stretches to provide tons of freedom and mobility. The water repellency is a bonus for those drizzly Northwest days or snow showers. I’ve worn mine climbing, biking, kayaking, running and skiing. It can also function as a lightweight insulating layer for cold conditions." – Ed Viesturs, Mountaineer Features: Usage: Cool and Cold Weather Aerobic Weight: 0 lbs, 13 oz / 376.00 g Center Back Length: 28" Body: WINDSTOPPER® Soft Shell Articulated sleeves Long cut back Rear zip pocket Windproof and breathable Inner cuffs with thumb loops Interior MP3 pocket with earpiece cord exit Full front zipper with internal draft flap/chin guard Stretch side and sleeve cuff panels 360 degree reflectivity Fully taped construction with brushed taping Slim fitting hood for under-helmet use Close-fitting, athletic cut Updated fabric and fit
