### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    SO GOOD but size up
  

*by A***N on Reviewed in the United States on March 15, 2023*

These were just as good as the $60+ Patagonia and north face ones I bought my girls. They are super soft, great material and actually keep the kiddos warm however the only thing I would say is you need to size up. Both my girls are pretty petite (my 2 yr old still wears 18-24 months in regular clothing and most TTS 2T are usually a little oversized on her) and the 2T was still pretty snug. I would have sized up to a 3T

Too small

### ⭐ 1.0 out of 5 stars







  
  
    SO SMALL
  

*by L***R on Reviewed in the United States on October 30, 2023*

Bought this in a size up but it was so incredibly small she could not even fit it over her head. I purchased a 2t and it fit more like a 9-12 month.
