This is L.L. Bean's famous "Wicked Cozy" fleece blanket. It is incredibly thick, plush, and soft. It feels luxurious because it's so soft and silky. L.L. Bean says the fleece is double-brushed for extra softness. The fleece is known as "Luster Loft" and is 400 GSM in terms of weight, which is considered quite heavy for fleece. The fabric is 100% polyester. To keep it soft and fluffy, take care to machine wash it in cold water and then dry it with no heat (fluff cycle). Or you can hang and air dry it. It's also advised to wash the blanket separately from other laundry, so that it has plenty of space in the washing machine and the fleece isn't affected by other types of material/fabric. This blanket is twin size, which is 88 inches long x 60 inches wide. The color is "Raven Blue," which is a medium blue -- not quite as dark as navy. This blanket was barely used and only washed 2xm with fragrance-free laundry detergent. Both times it was air dried. It is in excellent condition and still soft and fluffy. It has no weird smells (no smells at all) or stains. NOTE: The $80 price takes into account the $9 I will have to pay Poshmark to send this blanket -- as the package will weigh more than 6 lbs. when boxed up. In other words, the price is effectively $71 since I'll have to pay Poshmark $9 in shipping overage. Fyi, the blanket retails for $119 when new.
