The Oalyip is a big-and-tall rectangular sleeping bag with a cotton flannel lining, a water-resistant shell and an oversized removable pillow. It measures about 78.7 inches long plus an 11.8-inch foot section and 35.4 inches wide, so it fits larger adults who find standard mummy bags tight. Its ratings are comfort 41°F, limit 32°F and extreme 23°F, which makes it a three-season car-camping bag rather than a true winter or alpine bag. The right-side zipper lets it pair with a left-zip bag into a double, and the foot zipper opens for ventilation. Against mummy bags it trades packability and weight for room and a homier flannel feel.
