The build quality of the Kayak is good. The design is like a hybrid between a canoe and a kayak. The drop stitch technology enables that kayak to be inflated to high pressure (10 PSI). So, it holds a cube-like shape and feels as rigid as a hardshell kayak, but is very easy to pack down and stow away, and light enough to carry on your back for short or medium distance walks.
I purchased this as a secondary Kayak for when I bring along a friend/family. It was easy for a beginner to use. Over a 10km paddle, the performance was great. It tracked well and was reasonably fast. There seems to be one minor imperfection in the drop stitching in one spot on my product, but it doesn't seem to impact performance and does not seem to be causing any issues. If it does, no worries, as the manufacturer (Aqua Marina) provides a 1-year warranty on their inflatable yaks.
