Proteus Short John 5/4 mm - Men's - M

Short John Wetsuit
Using 5/4mm thermoflex neoprene with a super smooth outer lining, the short john is designed to be worn underneath the 5mm or 7mm Proteus to provide enhanced body core protection.
With no zips, the short john is both comfortable and practical, often actually making it easier to don the full suit on top, thanks to the low friction exterior.
