Technical fabrics wick: they move moisture along the fabric and let it evaporate. That is\nexcellent in a shirt and less useful on a forehead, where what you want is for the sweat to be\nabsorbed and held rather than moved somewhere else.
\n\nCotton absorbs. It is heavier when wet and it takes longer to dry, which is exactly why the\npack has three in it.
\n\nA band tight enough to leave a mark is too tight, and by the end of an hour it will have given\nyou a headache. It should sit without being pulled down, low enough to catch sweat before the\neyebrows, high enough not to touch the eyelids.
\n\nIf it is riding up, it is too loose or too high, not too small.
\n\nSalt from sweat is what stiffens a band and eventually kills the elastic. Rinse or wash after\nuse, and dry flat rather than balled up in the bottom of a kit bag. That is the difference between\na pack that lasts a season and one that lasts three.
\n\nThey are fine in a normal wash with everything else. Avoid fabric conditioner: it coats the\nfibres and makes cotton less absorbent, which is the one thing you are buying.
\n\nThe obvious uses are running, tennis and basketball. The less obvious ones are the reason\npeople buy three packs: gardening in July, DIY in a loft, and any job where your hands are dirty\nand your hair is in your eyes.
