Good quality
Size: Large, Color: Golden Yellow
This was true to size and is a nice quality sweatshirt. It is soft but not buttery soft. It was a good value since my child wanted it for part of a Halloween costume. He has worn it again which makes the purchase even better

Excellent quality, but difficult for dressing
Size: Small, Color: Light Brown
My son practically lives in these. The neck opening is a bit tight (hard to get over his head when dressing), but they're very warm and soft. Good quality fabric and nice colors.

Love it, slim fit, a little tight pulling over the head.
Size: X-Small, Color: Golden Yellow
Overall, this is a really quality sweater. It’s very soft the materials on the thicker side. The color was beautiful. The body fit was perfect, but it was tight fit, pulling it on and off over the head. That being said my child is on the smaller size so it is more of a slim fit overall, I’d recommend sizing up! Other brands he wears a 4T shirt and we purchased an XS (will be getting a small in the future to compare)

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.
