Cycling to work though the rain this morning got my me musing over the possibility of using hydrophobic spray to treat my mid-priced soggy DHB bib tights into something that could perform like the more expensive castelli nanoflex garments. My main gripe with cycling in winter rain is the cold wet feeling on my exposed thighs. Remembering something I watched a few weeks ago on some gadget show on the telli where hydrophobic spray was used to waterproof everyday items making them impervious to stains and water, I wondered if maybe if I could simply by a £10 can of the stuff and turn my bibs into high performance, exotic cycle gear. Hydrophobic spray covers stuff in tiny little nano rods which are so close together that water droplets don’t touch the fabric and simple bead up and fall off. Sounds good, so long as these nano-rod things don’t get in the way of breathability, but the show didn’t mention that.
Anyway, I’m tempted to take the plunge and try it out for myself, but before doing so I want to ask if anyone here has tried this yet? If so what were the results? Does it affect the breathability of fabric? Does the water proofing work on stretched lycra? etc
