This is a water-repellent active romper from Brownie's. The inside is made of boa fleece material, which is warm. There is some slight pilling on the shoulders where the harness rubs, but it doesn't affect use. There is no extension fabric for the belly for girls. It's a size M, and my dog, who weighs 3.5 kg, fit perfectly in this. I'm also selling a different color in the same size. - Brand: BROWNI'S - Colors: Pink, Navy - Design: Snow wear - Inner Material: Boa fleece - Features: Waterproof Thank you for looking.
