I have seen towels like these on Ebay. Curious about whether they actually add anything beyond what a regular towel does. (Usually shower before shaving anyway, though, so such a towel is perhaps redundant anyway..)
Well they are a little different from your usual bath towel. They have a herringbone pattern to make them strong, are flatter not as fluffy with the knap of a bath towel, and hold steam very well. I got them for a couple reasons, they are smoother on the face, washcloths with their knap tend to be rougher in my opinion, their size 16x25 is better for face application than a wash cloth, and also for wiping off my straight razors. So I usually use two per shave.
