I gave this sleep sack 4 stars based on what I knew I was getting-a polyester mesh sleep sack!  I'm not sure why people are giving bad reviews for not reading the title or description correctly (or at all).  I would love a cotton sleep sack to be made, but in order to stay within regulations for fire safety, it cannot be done in this larger size (only in the sizes intended for infants).

It is lightweight and is great for the warmer weather we have been getting.  The fleece sleep sack is much warmer, so this is great for spring and summer.  The sack is HUGE on my 20 month, 35 in, 27 lb child.  (wears 24 mo clothing) I'm sure we'll be able to use it next spring.  The material right where the feet go through is a softer material than the mesh that the rest of the sack is made from.

I love the big pictures in the top of the sack.  It is perfect for toddlers to identify and love.  My child does not like blankets, but insists on wearing his "car sack" or "dino sack" to bed.

My only complaint is the tag- this goes for all of the sleep sacks we have owned- it's huge!  It is always flipping upside down, and tickling my son's neck.  The tag is a softer material, but I just don't like tags in young children's clothing.  To make this sack perfect, I would like a tagless version!
