At first touch, it may not seem like much. But don t let this jacket s incredible light weight fool you. It s as cozy as down (seriously!) with 100-gram PrimaLoft insulation providing the warming power. The shell is also windproof to protect against blustery breezes. A water-resistant finish sheds rain, snow, sleet. What s more amazing is that it even packs into its own pocket, so you can bring it anywhere. 100% polyester shell. Machine wash. Imported.
