Have you been thinking about becoming part of the fastest growing water sport around? Stand-up paddleboarding or SUP is fun, easy and very, very popular. But do you know what to look for in inflatable SUP technology when you're ready to make that investment? Here are a few things to think about: When compared to composite boards, inflatables are much more durable. They are lighter than plastic SUP boards. Portability? You bet. Far more portable than hard boards. Advances in SUP technology are allowing Air Kayaks to offer inflatables that rival hard boards in stiffness, giving you the speed that, until now, has been hard to find with inflatable SUPs.
