The Women's R4 5/4/3mm Hooded Wetsuit from Patagonia.
Spend a week scoring uncrowded waves in Alaska with the right suit, and you’ll start to think that warm water is way overrated. The redesigned R4 Front-Zip Hooded is the warmest wetsuit Patagonia offers, with high-quality neoprene and a merino wool and polyester lining for unmatched warmth, strength and flex.
Features include a heavyweight wool and recycled polyester lining in the torso and thighs to maximize warmth, with a new mid-weight wool and polyester lining in the hood, sleeves and lower legs for increased performance and stretch. Critical seams in high-stress areas are secured and reinforced for strength.
