The Hyperflex AMP wetsuit hood is an excellent accessory for colder days. The double bib system layers perfectly with your existing fullsuit collar, and acts as an anti-flush gasket to keep cold water out. The sealed seams and poly fleece lining work together with the gasket to provide a semi-dry experience in the water. 100% superstretch neoprene moves with you, not against you. Also features a cinch cord at face for a tailored fit, a sun visor, and wind resistant mesh skin exterior. Sweet hood at a sweeter price!
