KING is the world's largest outdoor products chain retail organization, covering a comprehensive outdoor product management, large-scale comprehensive brands need to take into account a variety of categories, relatively in technology research and development is not as good as the franchise brand, so it is more necessary to control product quality, KING has established strict audit standards, but also set up an outdoor tourism department, by the actual experience of employees, so that not only feedback the effect, but also to provide consumers with detailed information. KING also has an excellent membership system, and is the most membered outdoor brand in the United States, and in addition to selling private label products on KING's website, other well-known outdoor brands such as Mountain Hardwear and Marmot also sell products.
 
"Novara, by KING" is KING's own brand, of which KING Co-Po is responsible for the operation of sleeping bags, known for its richness, not only including traditional mummy, envelope sleeping bags, but also suitable for women and children, fully considering the needs of various groups, the size is also divided into regular or extended forms, so KING can buy a complete range of sleeping bags for home camping in one stop.
 
From the outside, KING also put a lot of thought into the overall structural design, with insulating yokes to fill the neck and shoulder gaps, and vertical stoppers sewn into the side walls to fully avoid heat loss. The knees of the sleeping bag are wider, and the feet are sewn into trapezoidal compartments, giving the user plenty of room to turn. The hybrid zipper path combines the zipper and the internal anti-slip strip for easy user access. Sleeping bags for women increase hip space, shorten shoulder width, and increase insulation in key heat areas.
 
KING is also not stingy with the use of technical fabrics, for the down sleeping bag with higher waterproof requirements, the use of Pertex nylon fabric, with a durable and waterproof DWR coating, to ensure insulation, and at the same time improve wind resistance. In addition, 20D tearproof nylon is also used, although at present, in the world, in order to pursue lightweight, the trend of fabrics is getting thinner and thinner, but it will also bring the risk of reducing the efficiency of warmth and maintenance, so 20D is still the most suitable fabric thickness.
 
KING uses down and synthetic cotton in its sleeping bags, which are currently the two most common types of insulation materials used in sleeping bags. The down is fluffy and warm, the expansion of the KING down material can reach the highest 850 at present, the Magma sleeping bag filled with goose down is the one with the highest warm-weight ratio in the KING Co-op series, and there are 700 expansion duck down filled Igneo and Joule Women's, the filling volume of the sleeping bag can basically reach half of the total weight, and the price of the down sleeping bag is mostly between 300-350 US dollars.
 
Synthetic cotton is filled, waterproof is better, and can be used even after wetting, KING mostly uses synthetic cotton in three-season sleeping bags such as Trail Pod, but the fluffiness of synthetic cotton is poor, the packaging volume will be relatively large, and the warmth also needs to be assisted by the vertical lining structure or sewing process, Trail Pod uses a shingle-type structure with overlapping layers to make synthetic cotton evenly distributed, and there will be no cold spots, and the price is $100 respectively.
 
The fly in the ointment is that KING has not yet entered the Chinese market, and can only be purchased through overseas official websites in China, and the delivery process is more rugged, which is more suitable for outdoor enthusiasts with overseas shopping experience.
