From ION's point of view, even the smallest items in the product range deserve the same dedication and precision as every complex item. Therefore Neo accessories are a small but essential part of the whole equipment and sometimes these small items decide whether you have a great day on the water or you go home in deep frustration. This 2mm neoprene hood fits snug and has a small brim to keep the water from running into your eyes. If your head is warm your body stays warmer and you can stay on the water longer!
