An impact vest is essential to wear whilst wakeboarding. the foam padding dampens the impact from the water if you crash. The neoprene material is stretchy and flexible and allows freedom of movement. the impact vests have standard clash foam for excellent absorption then others have added NBR foam in critical areas for refined protection and flexibility. The NBR foam doesn't absorb water meaning the impact vest wont drag you down in the water when it gets wet. The Mystic Shred Front Zip even has a NBR spine protection. Most of our Mystic Impacts Vests come with front zips making it really easy to get in and out of.
