Stand-up Paddleboards are light, but their beam and thickness often make them awkward to lug around.  Here's a very simple and inexpensive solution for carrying your SUP.  This Paddleboard Carry Strap features:

• Extra large and extra thick shoulder pad.
• Adjustable straps to accommodate boards of different sizes (up to 81" circumference)
• Convenient loops that allow you to store the paddle or even use the paddle as a carrying handle
• Shock absorption system to facilitate longer walks
