The Sol survival towel is easy to toss in your pack for those long days on the trail when you need something to dry yourself, your gear, or clean up some grime. The towels are slightly bigger than a golden dollar when wrapped and are 12" x 24" unfolded. They can be expanded with or without adding water and can be used wet or dry. These towels are also durable and meant to be reused. Just hang to dry!
