School or sport (ie Adidas, Nike, etc) gym bags are strong but being made of nylon can become warm inside, particularly if the captive is hooded for "long periods" or in a warm/hot climate.
Being made of cotton, pillow cases are more comfortable to wear but not as effective as hoods because being thinner the captive (unless they are blindfolded as well) can see through them.
Edinburgh University's Gift Shop includes cotton gym bags in their range, but like pillow cases they are more comfortable to wear and not as effective as hoods. Check your local university or school shops to see what their gym bags are made of? The "Insert Image" function doesn't work!
You have to make a choice - comfort or effectiveness?
