Affordable underwear that wicks rain
When there's a small chance of rain, say 10%-30% chance, I tend to take my chances and shy away from rain pants. Sometimes I wear polyester jeans instead of cotton jeans, as polyester does a decent job of wicking away rain drops. If I get caught in a light rain with the polyester pants, my legs get slightly damp, but not uncomfortably so. The trouble is, my underwear gets wet. This is partly from sitting on a seat that gets wet at red lights, and partly from the rain drops that land on my pants. In the end, I get to work with dryish pants/legs, but wet underwear. I rarely see underwear that is anything but 100% cotton.
Does anyone know of affordable underwear, for everyday wear, that won't absorb rain? Thanks.
