I love these things.  I do a fair amount of outdoor excursions, and this is one of my standard EDC (every day carry) items among or away from civilization.  It's great aerated shade in hot environments, also in cold environments scrunched up or folded is good for warmth insulation, and regardless of the weather the design looks quite fashionable as well.  Not to mention the nearly endless list of uses a bandana has in general, any boyscout or survivalist/bushcraft people out there know what's up.

I ordered the Olive Drab color and the Blue.  They are definitely higher quality than I was expecting.  100% cotton, nice and soft.  I am pleased and will order again.
