Review: Cute and functional - These are great because they’re not too thick. Just right. They’re a little big but not an issue. Great because they have the area at the hand that folds over. Definitely recommend and would purchase again.
Review: Super cute! - These are great! I like that they are long sleeve to keep baby’s arms warm, but are thin and not like most long sleeved sleek sacks you find. They seam like they’re comfortable for baby to wear, wash nicely and haven’t worn out at all. The sleeves did seam a bit too long, but we just cut them a little shorter and they’re perfect. Used for my first baby at least 6 months and now using with the second.
