The Nano Puff Jacket from Patagonia is designed for changing weather conditions. With a sleek design, the Nano Puff is made to trap heat and block the wind. The 100% recycled polyester shell is constructed with a water-resistant DWR finish, and its low-bulk, highly-compressible design is loaded with 60g of PrimaLoft Gold Insulation for warmth in cool weather. The shape of the Nano Puff features horizontal quilting on the side panels for a flattering silhouette, and the interior storm flap with zipper garage provides next to skin comfort. The internal zippered chest pocket is ideal for holding valuables and doubles as a self-stuff sack with a carabiner clip-in loop. This jacket also features two zippered hand warmer pockets, elasticized cuffs and an adjustable drawcord hem to keep wind at bay. 100% Recycled Polyester Ripstop Shell and Lining w/DWR Finish, 60g PrimaLoft Gold Insulation, Brick Quilting Pattern and Narrow Horizontal Quilt Lines on Side Panels, Center Front Zipper w/Wicking Interior Storm Flap, Two Zippered Hand Warmer Pockets, Internal Zippered Chest Pocket Doubles as Stuff Sack w/Reinforced Carabiner Clip-In Loop, Drawcord-Adjustable Drop-Tail Hem, Fabric is Certified as bluesign Approved, GTIN: 0889833308695, Model Number: 84217 BLK S, Product ID: 513640, Model Year: 2020, How Does This Fit?: True To Size, Warmth Factor: Warm, Wind Protection: Yes, Waterproof Zippers: No, Breathability: Not Specified, Waterproof: Water Resistant (< 5,000mm), Insulation Type: Synthetic, Length: Hip, Jacket Fit: Regular, Type: Insulator, Race: No, Battery Heated: No, Warranty: Lifetime, Breathability Rating: N/A, Waterproof Rating: DWR Finish, Taped Seams: None, Insulation Weight: 60g PrimaLoft Gold Insulation, Exterior Material: 22-Denier 100% Recycled Polyester w/DWR Finish
