I absolutely love this! I waited for black Friday to see if it would go on sale, because it's a lot of money for one sleep sack. Honestly, they are phenomenal. Especially as my little guy is sick right now, so I'm happy knowing that it can help him regulate his temperature (or that's what they say at least). Anyways, I only bought 3, but I wish I bought more; so hopefully boxing day will have a sale.
Side note: I have PPA and other sleep sacks heightened my anxiety with worry of them slip...
