This new 2008 LF Impact Vest design is thinner and softer than any other impact vest on the market. After analyzing riding sequences, our engineers noticed the importance of fluid movement in the shoulder region, and then incorporated dynamic spacing into the Impact Vest. This vest combines style, comfort and safety. We designed this vest for people who use a vest for Kiteboarding as well as other sports such as wakeboarding and tow surfing. Although the LF impact vest was designed to be used specifically with our own LF waist harness, it also works with other waist harnesses as well.
