I know about the MEC towels but they are quite expensive compared to a "shamwow" type thing. And since they look to be made from a material that is similar to the t.v. ad towels, I thought I could save a couple dollars and put them on other bike related accessories. To me, a 20 dollar light towel that looks like it's gonna rip apart in a week doesn't look like a good investment.
Thanks to for info on the non-working shamwows and working cheap car towels I'll probably try those instead. A normal towel just seems so big to carry and doesn't dry fast enough after use.
