There's nothing like the convenience and ease of biking to work — you save on gas, avoid traffic, and it helps you stay in shape. But, there's nothing worse than the wet ass that comes from biking on a rainy day (and the jokes you get when you show up at the office). Ass Savers Emergency Mudguards ($11) solve that problem, and stop the ruthless jokes. These simple polyurethane tabs fasten beneath your seat, catching all the muddy, wet spray from your rear tire. They come in a range of bright colors, or black and white, and tuck underneath your seat when you don't need them.
