This is an homage and extension to the the Socks Machine idea, which is exceptional, in and of itself. With inspiration from Samsung, I will take it one tiny step more.
If you have a single pair of socks and underpants you enjoy using; simply remove before going to bed, and insert over foot and pelvis meshes on a device by your bed, and close the lid. Overnight, the underpants and socks get flushed and soaped, rinsed and dried -- and then critically warmed -- 20 minutes after you awake, with very little shrinkage. This give you enough time to pop out of the shower, open the lid, and then apply toasty wool to your nethers before commencing the daily damp and cold commute.
Then, that night, you re-place your work pants and socks and save the naughty ones from excessive use until the weekends.-- mylodon, Oct 06 2017 Socks Machine Socks_20Machine... just needed warm pants.

Maybe this device could cool or warm your kecks depending on the weather?-- hippo, Oct 11 2017 "He looks like butter wouldn't melt in his underpants..."-- pertinax, Oct 13 2017 random, halfbakery
