Two sleeps sacks both are 1.0 tog. Black is a new sizing small has some pilling and pinholes in the lining see pictures. The other sleep sack is old sizing 6-18 months. It accidentally got bleached so it was blue not purpley. Still very soft. Some piling no holes. Both still have a ton of life and use my son just out grew them. Quick next day shipping. Smoke free, pet friendly home.
