Laugh if you like, but these have become standard issue winter riding wet-weather gear for me. They cost $3 and work great. They even fit inside my normal bike gloves if need be.
Be sure to get the flock lined ones – otherwise you won’t be able to get your already damp and cold hands into them.
Two years ago we did a ride to Bellingham in November. We left at 6am – at 6:15 it started raining and didn’t stop for 13 hours. We were completely drenched. In Mount Vernon I grabbed a pair of these since everything else I had was soaked through – was impossible to get warm. Best $3 I spent that day.
