It's a really good jacket, stylish and above all comfortable. It washes easily and is a basic item in a child's wardrobe super versatile and useful. I'm delighted with it and it arrived quickly.

Perfect!
Size: Small, Color: Streamwash
I ordered a size S for my grandson who just turned 6. It was a little large, but roomy so that he could wear it over layers. The jacket is well made from a soft light weight denim. It was easy to add an iron-on patch to embellish the back of the jacket. Good price and value.
