This is a BEAMS x mont-bell collaboration product. I threw away the tags, but it's only been tried on, so it's like new. The size is unisex XXS, which corresponds to a women's S size. The color is olive green (close to khaki). It's a light down jacket, so I think it would be good as an inner layer. I have pets indoors. Please refrain from purchasing if you have allergies. [High Heat Retention] This mont-bell outer uses 800 fill power down, providing excellent heat retention. It is designed to keep you comfortable even in cold environments. - Brand: mont-bell - Size: XXS - Down Grade: 800 - Color: Olive Green - Design: Button closure - Material: Nylon Thank you for looking.
