I've had these now 3-4 months and use them inside of other large gloves. They're very warm and have held-up. I tried to just wash them in a bowl of soapy water then hang out to dry, and that has worked fine. I've used them as liners in -10F and even colder this year ice fishing and they have been great. And for cleaning fish outside under durable rubber gloves (which you can get for like $7 at harbor freight...tip of the day)... great. No freezing, no cold, work well so far.
