The surface of the inside of my helmet, and some of the adjustment band has become sticky and seems to be in the early stages of dissolving. The only possible cause I can think of, given that its not been that hot, is that a liberal application of sun screen to my head may have caused a reaction. The helmet is a standard Hex, and the sun screen alcohol based. Either that or maybe I have acid sweat!
Any one else similar issue, and if so suggestions on how to avoid stripy, helmet ventalation slot sized, sunburn stripes please.
