Gotta have the real stuff! The Airblaster Women's Freedom Down Jacket is filled with the insulation that mother nature herself designed specifically for keeping cute baby ducks warm and cozy, aka down! More specifically, this jacket is chocked full of fluffy, luxurious, 500 fill power down. 10K waterproof shell won't rip or tear easily, and critical seam sealing brings the weather proofing up, while keeping the price... waaaaaaait for it... down.
