The North Face Blue Kazoo 15-Degree Sleeping Bag has 600 fill down that plays a toasty tune down to below freezing temps. Extremely compressible and durable, this is the classic North Face all-around backpackers bag. As usual, The North Face has constructed this bag with the utmost detail. Listing all of the Blue Kazoos technical features is enough to put you to sleep, so well cut to the chase. Its silken lining feels wonderfully soft on your skin, and its breathable so your funk doesnt fester inside your bag all night. Heat traps and draft tubes minimize heat loss throughout. The Blue Kazoo is so comfy, youll say to hell with seeing the sun rise over Lone Peak, and instead choose to sleep in. But just in case, The North Face has integrated an ear-level watch pocket so youre up in time. When you go to rest your weary head, stuff the Blue Kazoos external pillow pocket with your down or fleece jacket and voil Instant pillow. Store your Blue Kazoo in its nylon/mesh storage bag so the down doesnt lose its loft and pack it in its stuffsack when youre on the go in the backcountry.
