Going backpacking for a year and wondering if those travel towels are worth getting?
Hey I have found mine absolutely invaluable, through Thailand, China, and Cambodia, I have been offered a towel in a hostel twice in India! I would say take one.
Definitely, but make sure you get a good one. I use a large Paramo travel towel - www.paramo.co.uk - and it has worked great so far. A normal towel is much more likely to get smelly very quickly and also takes much longer to dry.
I think I just answered another one of your questions on vaccinations! I used a travel towel around europe- one of those special towels that quickly absorbs water and such. Honestly, after a week it really started to smell. I would say start with one but you may end up chucking it. what I have as an alternative is just getting new towels as you go along. If traveling in asia they are dirt cheap.
Personally I have a bad habit of losing towels - I leave them behind in rooms and bathrooms a lot! So, a travel towel would have been a waste of money for me. (Confession: I've never owned one of those special travel towels). Also, buying a new towel as you go along is not expensive, but if you've spent a lot of money on a special travel towel you might be a bit pissed off when you lose it!
I would definitely say take one! I have a great "large camping towel" that's microfiber and super-light. It's come in handy more than a few times and since it's not big and bulky, it doesn't even get in the way. Go for it.
