Had to use my Pocket Rocket for only the second time today. Oddly, as soon as it got wet, it went very wrinkly. When I got home, my jersey was soaking wet too, so it doesn't appear to be very waterproof any more either. Like I said its only the second time its been worn. It has been washed once, in a 30 degree non bio wash (same as all my bike gear). Is it knackered now and only fit for the bin?
