I love the Aquis Adventure XL (29" X 55") and have several which I have used exclusively for the last several years. Graphite, Seafoam, & Blueberry. When I made a triip to my daughter's this spring, I took my L (large) towel to save space when I packed. I regretted that every time I used it - just to small as a bath towel. I really like the size of the XL and have one ready to go on my next trip. I have the smaller towels (15" X 29") which I use on my (short) hair and also as hand towels.
I have a couple of the yoga/beach towels that I don't use because of the size (24 X 68). The are narrower and longer than the XL and they are just awkward for me to use.
I only buy them when they are on GMA and View Your Deal.
