Passenger have been perfecting the Jack Pine Women's Jacket for three years to make sure it is the best it can possibly be. The Jack Pine is a reliable insulator which is durable and pleasantly lightweight. With a timeless style and practical functions (the jacket packs away into its inside pocket) this jacket is both brains and beauty. Passenger use 120g premium polyester to insulate the Jack Pine instead of classic down so the jacket is able to perform better in wet conditions and has a better warmth to weight ratio. A DWR coating will keep you dry in mild precipitation and brushed tricot pockets create a safe haven for your hands on nippy days.
