Here's why you need it
Why wouldn’t you care about having an individually fitted harness? It keeps you riding longer, protects your back for years to come, and gives you extra confidence on the water. Other harnesses only consider your waist circumference to estimate your size. ION Curv harnesses take it two dimensions further to achieve your perfect fit.
Don‘t settle for less.
