Tracking-Camping Conical Sleeping Bag is an insulated covering for a person, essentially a lightweight quilt that can be closed with a zipper or similar means to form a tube, which functions as lightweight, portable bedding in situations where a person is sleeping outdoors e.g. when camping, hiking, hill walking or climbing.Sleeping bags are also extremely easy to clean as they are safer for machine wash too.They are incredibly roomy for any adult or child. It's easy to get in, get out and turn around to find a comfortable sleeping position. The zipper stays closed, and the plush filling means you'll sleep like a baby.The conventional size is more suitable for teenagers.
