Quality item and super comfy.
Size: XX-Large, Color: Light Grey Heather
Got this for my son to take on a field trip in case it got lost it wasn’t one of his expensive ones. Oddly enough it’s so comfy it’s now his favorite hoodie and he wears it all the time and keeps it in his backpack. Holds up well to constant washing.

WARM, not thin material
Size: Small, Color: Blue
Hoodie is comfy, warm and soft. Fits true to size, especially for a child who is a bit small for their age. Holds its' integrity in the wash. VERY happy with this purchase and will be buying more colors in the future.

I was delighted with the quality and color
Size: X-Small, Color: Lilac
This is a super cute, and frankly, fairly high fashion little hoodie. The price was great for what it is. Really nice soft (terry?) inside. Double fabric hood. Really soft. It has an oversized cut which makes it easy to get on and off, but is just the right length to make the sizing look great and intentional - it doesn't look too big. I love the color. It's high quality, and I didn't notice any shrinkage. Even the hood is cut in a chic way. Not your average kids' hoodie.
