This site has a broader range of print designs (e.g., basic first aid, wild animal & tracks, basic knot tying, clouds & weather, etc.)   The "night sky" one not only has major constellations, it also glows in the dark.  You might notice that many in of the photo's of me in the bush I'm wearing a bandana around my neck ... my choice is those that are the Buzz Off/Insect Shield variety ... no bug bites on my neck on portages!

They are most of the bandanas not particularly well made, but then then are not particularly expensive either and might serve as a diversion on a slow day in camp.  If not, you can always use another bandana (e.g., wash cloth, pot grabber, etc.)!

Quite expensive though for the printing job I'm guessing reasonable.  I pay less than $3 for one of similar size & good quality cotton.
