### ⭐⭐⭐⭐⭐ 







  
  
    Good sleep sack
  

*by M***E on Reviewed in Canada on 19 January 2024*

Baby is enjoying his new sleep sack. The nursery gets quite cold because it has very large windows but the sleep sack keeps baby nice and toasty. Zips up easily and the material is nice and soft. True to size and easy to zip up.One small thing is that I wish the inside was the same as the outside material of the sack as it’s softer than the inner lining. But it’s soft enough and well built. Good value for the price in my opinion. I got the print that was on sale.

### ⭐⭐⭐⭐⭐ 







  
  
    Soft and thick.

Very well made, attractive, thick, soft and fluffy. Definitely for cooler rooms as this is of excellent quality.
