Fleece at 330 grams per square metre gives this blanket real warmth for its packed size, dense enough to cut wind chill on an exposed touchline yet soft enough to drape over shoulders through a whole evening. A PU1500 waterproof rating on the backing repels rain and damp ground, so the blanket works as a groundsheet at a picnic or a beach as readily as a wrap in a stand. Ultrasonic quilting bonds the two layers together across the panel, which stops the shifting and bunching that stitched-edge blankets develop after a few washes. Flame-retardant treatment suits use around a campfire or a fire pit. Unfolded the blanket measures 82 by 55 inches, wide enough for two adults seated side by side, and it compresses into a backpack at just 2.76 pounds. Machine wash cold and tumble dry on low heat.
