18-24mo Sloomb Basewoolies (100% merino wool). These are in "light play condition" due to staining (check photos). It's possible these stains could be sunned out, but I haven't tried and cannot guarantee it. I'd say they are felted down about a size smaller. Still has flop and softness, but not like new. These have been well-loved. I can't find any thin spots in the fabric. We used these outdoors as a base layer and they are very cozy and warm. I also used these as a diaper cover and have lanolized them in the past, but it's been about 3 years since I've done that. I just hand-washed these in a gentle wool wash and they were laid flat to dry. Smoke-free, pet-friendly home.
