Thomas Fetterman offers loftstrand crutch users lycra crutch covers in a variety of colors including ocelot. These are created by Broken Beauties which offers similar covers for ancillary crutches and designer walkers.
Allman Products has a leopard print walker bag. 1800Wheelchair has a couple of bags that aren't all together ugly as does Canes Galore.
Okay, I'm going to be honest. This has been an altogether depressing post to research and write. I started it because I ran into a former student who was sporting some cool crutch skins . Now I am realizing "cool" accessories are pretty much non-existent outside of those skins. Perhaps there is someone who will read this who will invent something very cool. If so, please let me know!
P.S. That has happened to me before. I also run a diabetes and insulin pumping website and have a tee-shirt to my credit in addition to some grateful pump carrying case companies. So have hope, maybe in a year or two cool accessories will emerge.
