I had a standard sized one. I wear a 46 Short One Piece 'Stich, and my legs are...chunky. It worked great until... I stuck my leg out at a funky angle into the wind going at an unspecified rate of speed, and weee! The wind gremlins took it.
Cheaper than a GPS, but it will make you paranoid -- "Is it still there? Is it still there?" Lol. (Posted on 4/8/13)
I bought this with the magnetic fuel tank holder #194. This is the first Aerostich product that has failed completely to work. I have a full windshield but at speeds over 55mph the pocket flies off in the wind. It is too small to hold a full map folded and I have tossed it in a drawer while i figure how to make it earn it's keep. As a dunce cap maybe. (Posted on 7/24/12)
I bought the small one since I have skinny legs. But the small on requires you fold the map smaller and means more layers in the map holder and then I was going to cross the border from Alberta into Montana so I folded two maps so I could just flip the holder over when I crossed the border. I didn't flex the holder enough when I made the flip so some where in the next 100 or so miles (with a strong side wind) I lost the map holder. I still think it was so useful that I'm going to replace the small size with the larger size. (Posted on 10/17/11)
