The IST 5MM Hood with Triple Glue is performance tailored and designed for maximum comfort. The HDN0150 has an extended bib to guarantee a seal underneath the collar of a wetsuit. The Hood has different neoprene sections for the best possible combination of stretch and durability. The face seal is lined with smooth skin to eliminate water transfer and the jaw/ throat area is designed to stretch to accommodate variances between users, while the collar, head, and triple glued blind stitching is designed for maximum thermal protection and durability. The top panel is double layered to create a vent to allow air or water to escape the hood to prevent unwanted pressure or bubbling. Match this hood with IST’s Super Stretch wetsuit as they are both the pinnacle in wetsuit technology.
