Has any one seen any kind of waterproof cover for a cycling helmet? I have seen this one; http://www.wiggle.co.uk/ProductDetail.aspx?Cat=cycle&ProdID=5360031429&N=Gore Helmet Cover II but I 'ain't paying £20 for one. The thought of perhaps trying out a shower cap had crossed my mind, albeit only briefly. I look enough of a muppet already. My Altura jacket doesn't have a hood, and I wouldn't like one as I fear it would restrict visability when looking over the shoulder/to the side etc. If it is chucking it down I usually put my thinsulate hat on under my helmet as it gives me some protection from a cold wet head which is nearly as bad as cold soggy feet. What do other people usually do - grin and bear it?
