I allways wear a nappy when I'm riding the bike as the valve that controls my bladder is right wher I sit on the bike and every time I go over a bump it leaks a little. But it's alway handy to carry a spare they've been used cover blisters ,cuts and as urine is sterile you can safely clean scrapes and grazes
Reckon by the time I get to work tomorrow morning the seat will be fully dry.. unlike my backside...
