An insulating layer for paddling, surfing or swimming, made for those in-between days where a full wet suit is too warm. Updated fabric features more stretch and greater comfort so you can paddle your craft freely. Hydro Skin garments are meant to fit snugly next to the skin, similar to a wet suit. This allows for efficient performance and layering. 6 oz premium nylon/spandex with brushed interior; H2Core™ Rashguard underarm panels. Machine wash, line dry. Paddler-specific cut combines with friction-free seams to enhance paddling performance and comfort. Brushed interior for insane next-to-skin comfort. 0. 5 mm Terraprene™ neoprene with heat-reflecting titanium retains your body's warmth. H2Core™ Rashguard panels under the arms for increased breathability. Premium nylon-spandex exterior material offers optimal stretch and reduced water retention. The perfect choice when you need extra protection from wind, spray and cold water on cool days. Form fit restricts water entry, enhancing the insulation properties. Imported.
