My boy is a little below average and very skinny and they fit him perfectly. We have a lot of wool so I can say it was a little less soft and itchy and probably a bit more plump but it worked great and he's worn it a lot so I know they don't bother him. You are adorable on it. The coming weeks will be very revealing as to whether they help with warming, so I'll update them as needed then.
