These things are about as simple yet multi-functional as it gets! They can protect you from wind and sun in many different ways. Wear it just around your neck and avoid neck burns, wear it as a "dew rag" to keep sweat out of your eyes, wear it to cover your neck and face to avoid those nasty burns you can get out of the water from direct and reflected sunlight. That's just the tip of the iceberg with these things! Aside from the protection you get, they are small, very portable and dry fast. Once you start using this headwear you'll wonder how you ever got along without it!
