The fleece is thicker than I expected for a midweight, but it's still soft enough that my daughter doesn't fuss when I zip her in. Wore it over a onesie on a chilly evening walk and she stayed warm the whole time.
The recycled fleece feels substantial without being bulky, and my daughter wore it comfortably on a breezy evening at the park. The bear ears are a cute touch, though the sizing runs a bit small so I'd go up one.
