The other day I went to take my Wood Duck out. Checking it out before loading it on the truck I found that my NRS flotation bag (aft) was deflated. I figured no problem, probably a leaking valve. Started inflating it an found that the inflation tube had deteriated. There were cracks all up an down the tube, completely useless. The forward bag was still in good condition. I bought these this past April. I assume they should last longer than this. Has anyone else had this problem with the bags? I still went out paddling but I thought for $50 I should get a better product.
