The Fourth Element Neoprene 5mm hood has a smooth Glideskin interior and is produced using stretch neoprene to provide a comfortable fit. The short collar suits both dry and wet suits, and micro holes in hood vent air with minimal water ingress.
Hydrolock Seams are double seals that virtually eliminates water ingress into the suit. An internal back panel prevents water entering through the zip from reaching the back. The neck collar is lined with glideskin neoprene and fits snugly around the neck giving a smooth, complete seal.
The hydrolock inner neck seal is designed to fit snugly on the neck without being too tight. It can be relaxed a little by stretching it over a pudding bowl or diving cylinder overnight.
