Never heard of the Gutr. I used to use Headsweats headbands and always carried one or two spares while riding because the got so soaked with sweat. One season, while cross-country skiing, I purchased a Halo headband. Absolutely hated the thing. Didn't really do what it is supposed to do. The past year, I've been riding with a Headsweats Coolmax Classic. The tails are silly. I'll look into the Coolmax Shorty. In addition to the advantages already mentioned, it keeps the top of my head from getting sunburnt, (I do wear a helmet).
