I bought a couple of pairs of these having seen them advertised as 'the warmest leggings you will wear'. And they are! I feel the cold terribly, and these have really helped. My question is, do they wear and wash well? I wore a pair a couple of times, and the amount of fluff (I'm guessing the faux fur bits) that they've shed is a bit annoying. I've seen they are hand wash only, but will they survive on a delicates cycle, or will they go bald and sad and useless? Thanks!
