Flylow Charlie Jacket - Women's 2012: Packable and practically perfect, the Flylow Charlie Jacket offers the down jacket design we all love in cold dry climates, but with the waterproofing and venting needed to carry out high output skiing. Using new stitch through construction found in down sweaters throughout the market combined with packable 10k/10k, 2 layer polyester shell material, Flylow has created a waterproof down jacket that is as packable as your favorite down puffy but suited for the elements.
