Picasso Grab Straps
Brilliant idea by 3 x Australian Champion Andy Ruddock, Grab straps are made from double sided Velcro.
When wrapped around arm or leg the straps not only bind together, they "grab" to the nylon exterior of your wetsuit allowing no movement or loosening.
Other Grab Strap advantages are the lack of buckles to catch rig lines etc. and the ability to fit single handed.
