I found a pair of used dancer's warm up pants in a thrift store and I think they have excellent UL potential. And they are cheap too :)
Body Wrappers makes a full line of dance clothing. Their warm up pants are light ripstop nylon with an elastic waist and cuffs. Just plain pull-on pants, as Spartan as you could ask for, 3.5oz for size large on my scale and all of $20. The DWR on my used pair passes the sink sprayer test too.
