We love these sleep sacks -- they keep our little one so comfortable and cozy!
- JAVerified BuyerReviewingLong Sleeve Layer 0.2 TOG DragonfliesI recommend this productRated 5 out of 5 stars1 week agoWorks well
Keeps baby warm without overheating. Game changer for rooms that you can’t seem to keep warm. We use for temperatures 61-65F with pajamas that are long sleeve with pants. That works well for us. If it’s warmer than 68F, we typically use the pajamas listed above and a different sleep sack. But this is our cold midwestern US winter sleep sack bar none.
