World Famous Sports 3lbs. Sleeping Bag- Black
The “Euklisia Rug”, patented by mail-order pioneer Pryce Pryce-Jones in 1876, is considered by many to have been the first forerunner of the modern sleeping bag. Pryce-Jones, a Newtown, Montgomeryshire Welsh entrepreneur developed the bag and exported around the world in the late 19th century. Documents show he sold 60,000 of these rugs to the Russian army – and the British army also bought them. There are records of civilian uses too – among missionaries in Africa and pioneers in the Australian outback.
A basic sleeping bag is simply a square blanket or quilt, fitted with a zipper on two or three sides, which enables users to get into the bag and then close it up. A sleeping bag of this type is packed by being folded in half or thirds, rolled up, and bound with straps or cords with cord locks. The basic design works well for most camping needs but is inadequate under more demanding circumstances. The second major type of sleeping bag, sometimes called a mummy bag because of its shape, is different in a number of important ways. It tapers from the head end to the foot end, reducing its volume and surface area, and improving its overall heat retention properties. Some bags are designed especially to accommodate women’s body shapes. Most mummy bags do not unzip all the way to the feet, because the zipper is a weak point in any sleeping bag’s insulating qualities. Together with the tapered shape, this design feature helps protect the feet, which are more vulnerable to heat loss than other parts of the body. Another design feature is a drawstring, equipped with a cord lock, at the head end to help prevent the escape of warm air. A mummy bag often cannot be rolled like a rectangular bag. Instead, it is simply stuffed into a stuff sack or compression sack.
The bottom of a sleeping bag typically does not provide significant insulation, because body weight crushes the loft of the insulation material. It is therefore necessary to use a pad or other less crush-able insulation underneath the sleeper, especially in cold weather. Due to this, some sleeping bags do not include insulation on the bottom. Some include a sleeve for holding a sleeping pad. Additionally, some campers, especially ultralight backpackers or hammock campers, have started to use a top quilt, essentially a sleeping bag without a back. Some top quilts include a foot box, while others are just simple blankets.
