Kneeboard is made from highly durable and water resistant nylon.
I like that it uses a buckle, my prior was velcro and elastic, the velcro died and elastic was shot. This is shorter than my original. The map windows are a tight squeeze for a perfectly folder chart. The elastic e6b straps are useless, who carries their e6b anymore? I like the pockets one the front and the velcro for folding is closed. I wish there was a zipper pocket. The strap is about 1.5 inches and that feels a bit narrow on my leg and I have found (after 10 hours flying with this) that I have to move it as it constricts. Loosening allows it to rotate around my thigh. But I absolutely wanted the buckle strap so this is better than those elastic ones. The clipboard is a generic office supply store model. I will make my own insert for it, but I have to cut about half an inch off the bottom so it fits more cleanly into the kneeboard fabric. 3 start because the clipboard is too long, the strap too narrow and no zippers so things can fall out. But it does have a buckle and pockets and is not too intrusive otherwise.
