Whether you’re bush-wacking through thick brush or taking on a leg-breaking grade, this brilliant second layer piece will keep you cool and protected. The smooth, slick face slides easily under additional layers and great seam lines lay flat to prevent chafing. Pull down the extra long zipper for increased ventilation when mid-day sun catches you stranded in the middle of a set of grueling switchbacks or slip into the thumbholes for extra warmth and comfort when breaking camp in the morning chill. With plenty of stretch and breathability - including fast-wicking Omni-Dry technology - the Interval Deep Zip is the perfect piece for all your adventurous endeavors into the backcountry.

Armour®Stretch improves mobility and accelerates dry time with lightweight fabrics built in a 4-way stretch. Fabric Tech: 7.3 oz 88% Polyester / 12% Elastane. Imported.

You wouldn?t wear cotton boxers to swim in, just like you wouldn?t wear neoprene to ski in, so try what works best during aerobic activities in varying temps, and wear the Patagonia Men?s Capilene 3 Zip-Neck Top. This breathable, quick-drying, stretchy top retains heat while you sit at a belay station, and dumps heat when you unzip your jacket while skinning in the backcountry. Patagonia brushed the Capilene 3 Zip-Neck base layer and gave it flat-locked seams for comfort, compressibility, and easy layering.Product FeaturesMaterial: 100% Polyester (65% recycled)Insulation: MidweightFit: SlimThumbholes: NoRecommended Use: Skiing, snowboarding, ice climbing, winter activitiesManufacturer Warranty: Unlimited
