Good shout Graham and I've seen the like, though not used. But I've never ever had water 'blown' up my sleeves when riding and I've done some. Not saying it can't happen, just that I've not experienced it that way. I tuck any glove inside my sleeve when on a long run when raining, 'cos it's gravity that causes that wet feeling inside, with the water running down the sleeve and running into the glove above your wrist. The only time I get wet hands is when I've not bothered to stop and tuck 'em in. Yeuck!
