Blue and white Merino Kids standard weight sleep sack in good used condition. Size 0-24 months, runs TTS although my son is a very tall 21 month old and has outgrown it. Comparable to Woolino, with slightly different zipper configuration. This has been used and washed in free & clear detergent, but never dried. Zipper connection has come slightly apart (totally functional, but we did not fix) and there are a few small pulls / runs in the inner lining which do not affect functionality. We love merino sleep sacks for all seasons, but my son has outgrown this one. From Merino Kids: Our Standard Weight Go Go Sleeping Bag is an international award-winning baby and toddler sleeping bag.
