Insulation is made from 100% post-consumer recycled polyester fiber, which helps keep plastic waste out of our oceans. 150g quilted insulation offers excellent warmth, despite its low weight, and doesn¡¯t shift within the blanket. DWR (durable water repellent) coating provides water resistance. 20D nylon lining is very soft and comfortable against the skin. Integrated buckle easily transforms the blanket into a cozy, hands-free cape. Lightweight at just 25.6 oz, it also packs down small into the included roll-top nylon stuff sack. 4 corner loops help secure the blanket with ground stakes when desired, which is perfect for picnics. Your blanket won¡¯t blow away again! Great for indoor and outdoor activities such as camping, tailgating, picnicking, watching movies, and road trips. Machine washable (use a mesh laundry bag).
