Designed to regulate body temperature.The original Folly Zip Up hoodie was a great hoodie, but we knew we could make improvements. For V.2, we've updated the fabric to be more durable and snag resistant while also increasing the sleeve length. See, we do read reviews and listen to your input! This active hoodie still regulates your body temperature while effectively managing heat, due in part to the fabric selection which offers the perfect combination of softness, comfort and performance. Whether donned as a mid-layer for extra insulation or flaunted as an individual layer, this technical hoodie unmistakably outshines the rest.Features & FabricMoisture-wicking, body temperature regulating performance fabricSuper soft & stretchyFront kangaroo pocket with 2 zippersArmpit vent holesThumbholes at cuff48% Rayon, 45% Polyester, 7% SpandexWeight: 577g (taken from size M)Fabric weight: 350gsmShipping & ReturnsFast & free shipping on all US orders.Free returns/exchanges on all products.
