Two pilgrims will have three opinions about towels. I have observed that there are three schools of thought.
1. Folks who want to highest tech, tiniest towel they can source. Very often this results in something that is about the size of a hand towel or tea towel, the size you might use to dry the kitchen dishes or hang in a quest bathroom for drying hands. This will do the job, and dries quickly, but can be used for little else, due to the very small size.
2. Folks who swear by some sort of natural fiber or another in a wispy, fly weight fabric. Sarongs and scarves are along the basic shape concepts in this group. This is great for protecting one's private parts in a semi-public albergue situation, but the ability to dry natural fibers is open for discussion.
3, Folks, like me, who analyze everything to determine which solution provides multiple uses at the minimum size and weight, while still being fast to dry, easy to launder, etc. Each person arrives at THEIR preferred solution according to their needs and willingness to deal with trade offs.
Just for discussion, I use a standard sized YOGA Towel, by Gaiam. I obtained the one without the grippy dots. The normal use for this is to place atop one's yoga mat while doing yoga.
This towel is bright orange with pink piping around the edges. It was the orange color that attracted me. Here is my logic for trading off size and weight in return for this towels advantage of other types of hiking towels.
1. The towel when folded, fits in a one-gallon (three liter) ziplock bag. I sit on it to compress it to a very thin size. This rides in the bottom of my 38-liter Osprey rucksack. I can access the towel via the sleeping bag compartment zipper.
2. The towel is large enough to cover my priodigious self. I am a big guy and needed the length to wrap around my private bits. It is large enough to use as a blanket / shawl throw / cover on a chilly night.
3. The towel is terry cloth woven so it is outstanding at absorbing water.
4. The bright orange color makes it easy to locate in dim light, and it can be used for signalling in an emergency.
4. The fabric is microfiber, so it drys very fast.
My performance criteria were that any towel must:
- Cover me when coming to and from a shower.
- Be able to wrap, roll and stomp hand-washed clothing AFTER it dries me.
- Be usable as a cover or throw.
- Be quick-drying
- Have other uses, as determined by the exigencies of the moment.
So, in the end, and after several years of trying all the technical solutions out there, I traded off weight and size for über practicality, and went with the yoga towel.
Hope this helps.
