When it comes to warmth, wool is what’s up. As the world’s best natural insulator, its warming properties are second to none. Arcturus, a hunting and outdoor brand from Washington creates blankets from this amazing material, and they’re legit. Weighing in at 4.5 lbs., with a density of 550 GSM, their 64” X 88” blankets feature a 80/20 wool and synthetic blend and are loom-woven and hemmed on all sides with contrast lock stitching. Choose from a range of solid colors and stripes.
