WSP Premium 50" Colored Rescue Tube
Pros: Very lightweight and easy to carry around while roving/strolling. When in the chair, the material is of really nice quality and is smooth to the touch. It is durable and we have not experienced any cracking in the material itself.
Cons: Need a small nylon strap at the opposite end of the tube, not just the shoulder strap. When we first got it it was a little too slippery in the water when we were training. Overall we are pleased with the guard tube.
Note from WSP: We do have a tube with a loop at the end opposite the shoulder strap - #710T, rescue tube with reach assist. Take a look - it may be exactly what you're looking for.
