The MAGMA hood features a double flap: One stays outside the wetsuit collar while the other one comes inside. It creates a double barrier against water flushing and it makes sure the hood stays in place. We have used our Reflex-skin jersey to line the areas where we need mobility: Neck, face, chin. Head and ears are built in Glide-skin neoprene which is waterproof & windproof to fight the wind-chill effect. The inside is lined with our MAGMA fleece for an unbeatable warmth and fast-drying.It’s the weapon of choice if you want to spend the winter without brain-freeze while still having a good mobility.
