This sleep sack / wearable blanket is from Burt’s Bees Baby & is their “Quilted Herbivores” dinosaur pattern. This is made from organic cotton & is 1.5 TOG which is a warmer sleep sack for colder months or environments kept a colder temperatures. My son only really used it one night when it was cold in our home while our furnace was being fixed. It kept him nice & warm. We were glad to have it on-hand! 🚩 Know that while this is 1.5 TOG, this is NOT a weighted sleep sack. Weighted sleep sacks are not AAP approved for safe sleep, so I do not own/sell them.
