6mm XS SCUBA Standard HoodXS SCUBA's Standard bibbed hood elevates your wetsuit to handle colder water. This hood features a skin-in" rubber neoprene face seal to reduce flushing around the face. Glued and blindstitched seams further reduce water entry. The face seal area is also trimable to customize your fit to your face (please note: trim only after you are sure you're keeping the product. We cannot accept returns for hoods with trimmed face seals). The hood is 6mm and the large bib is 3mm.
