Convincing, weight / durability probably optimized. It could be bigger, but of course there should be more weight. The biggest drawback is that the tightening cords were only at two corners, meaning that square protection cannot be done with them alone.
Very handy and really light, but protective tarper. Ready-made fastening systems with quick-release locks, this is hardly easier to use! Slightly sticky to pack, but fits well in its packing bag. Good buy!
