The R2 2.5mm Back-Zip Wetsuit from Patagonia.
With high-quality neoprene and a merino wool lining that provides unmatched comfort and flex, the R2 Back-Zip keeps you warm through double-session days while the tropical storms crank out swell. Features include a new anatomical fit, 100% external seam sealing to eliminate leaks, a midweight wool lining in the torso and thighs for warmth, and a lightweight recycled polyester lining in the sleeves and legs for optimal performance and stretch.
The back-zip allows simple entry and exit, and enlarged PVC-free kneepads provide long-lasting durability. Critical seams and high-stress areas are secured and reinforced for strength.
