Xcel Polypro Hooded Thermal Fleece Lined Surf Rashvest Titanium glideskin lined hood with peak & elasticated face seal. Outer collar goes over your wetsuit collar for a decent seal to prevent flushes & the polypro shirt adds extra warmth to your winter suit. Serious cold weather kit. Note on Sizes Although a polypro will stretch we've found the sizes come up fairly small. If in doubt or between sizes we suggest you consider the larger option.
