The founder Jack Gilbert was the chairman of another outdoor equipment brand, Sierra Designs, with rich business experience and professionalism in product design, it is not difficult for Shanhao to get a share of the outdoor market.
 
Professional outdoor brands such as Western Mountaineering and NEMO basically have a number of patented technologies, covering down, fabrics and design, and Shanhao is most famous for its down treatment, Q.ShieldTM and Thermal.Q™ are the two masters, Q.ShieldTM technology makes down fibers permanently waterproof through coatings, and can maintain the best insulation performance even when exposed to moisture. Thermal.Q™ technology mimics the rigid stem structure of goose down, using stiffer fibers to fill the gaps in the down structure, providing better heat retention and good compression and rebound.
 
Most of Yamahiro's sleeping bags are also named after the patented technology used, and there are five series: Ratio, Women's Rook™, Lamina™, Phantom™, and Bozeman. Among them, the mid-range series of Ratio, Women's Rook™, and Lamina™ are more routinely used, and because Shanhao currently has foundries in Vietnam, India and other places with relatively low production costs, the price of mid-range sleeping bags is basically between 200-260 US dollars, which is more cost-effective.
 
In terms of form, compared with traditional sleeping bag products, which can only choose one of the two in comfort or easy to carry, Shanhao combines these two characteristics, the cut fits to the maximum, the head is lined with six vertical linings to maintain uniform fluffiness, the footbox at the bottom follows the natural foot position, and there is an additional 8-inch hidden expansion space on the right side of the sleeping bag, when the zipper is opened, the sleeping bag space and air flow increase immediately, while the weight remains almost unchanged, and the overall comfort is the best in the same class of products.
 
Ideal for backpacking and camping, the Ratio features goose down as the inner filling, Q.Shield™ technology to resist heat loss, and an open drawstring that can be easily adjusted with one hand for around $230. The Lamina™ series uses Thermal.Q™ technology for excellent compressibility and a Lamina™ spliced construction that maximizes insulation space and eliminates cold spots, and is priced at around $200.
 
Women's Rook™ sleeping bags have a total weight of 1kg, and the filling capacity accounts for 60%, which is enough to reach the temperature level required by women, and the velvet design is more in line with women's body shape, and the price is about $350.
 
If you're planning a pole climb, the Phantom™ is a great way to go, as the Gore-Tex fabric is lighter, more durable, resistant, warmer and more protective than regular sleeping bags, and sells for a relatively high price of $600 to $900. There is still a need for overseas shopping for Hiroshi Shan's sleeping bag in China.
