The adidas Originals Women's Firebird Track Jacket is a classic zip-up in Prime Blue, sized 4X and model HD2099. It's made from recycled materials, so it's a practical pick for anyone who wants an everyday layer that's a little kinder to the planet. It suits shoppers who want a comfortable, familiar track jacket for casual days.
It works well as an easy layer for errands, weekend outings, or a relaxed day at home. Check the size chart against your usual fit before ordering, since 4X runs larger than standard sizing in many cases, and pair it with leggings or joggers for a simple look.
Heads-up: Confirm the size and model number HD2099 on the product page before you check out to make sure you get the right jacket.
