We only use feathers tested by IDFL(INTERNATIONAL DOWN AND FEATHER LABORATORY & INSTITUTE) and produce sleeping bags tested by EN 13537 which is a European standard designed to standardize the temperature ratings on sleeping bags. Such attempts are not only seen in the country first, but met with global standards. We consider it our duty to give accurate information to the users.
Pertex is one of leading groups in outdoor textiles industry. Global outdoor brands especially prefer to use it because it has strong and lightweight properties. With Pertex Endurance, we have manufactured the world’s first tent made with Pertex Shield 3-Layer. The sleeping bags of extreme line are made with Pertex Endurance and ultralight sleeping bags for backpacking are made with Pertex Quantum.
ZEROGRAM is an outdoor brand that develops very lightweight backpacking equipment for adventurers by using innovative materials and design. Since 2015, ZEROGRAM has used goose down that is RDS Certified. RDS stands for the Responsible Down Standard, which is one way we help ensure the ethical treatment of animals. The RDS certified down is then treated with DownTek™ water repellent.
Pertex Shield DV 3-Layer is laminated by superb water-repellent ‘eVent’ membrane and it is applied to ZEROGRAM Papillon DV 2014. The passage of water vapor through a fabric is measured by MVTR(Moisture Vapor Transmission Rate) and the unit for the MVTR is g/m2/hrs. If the value of units is 10,000g/m2/24hrs, it means that the substance emits 10,000g per 1m2 : 10 liters of water vapour for 24 hours.
CORDURA® is exceptionally durable. As a byword for nylon 6,6(double-six) polymer, CORDURA® only offers their fabrics to businesses obtained a license from INVISTA, headquartered in United States, is the world’s largest integrated fiber company. CORDURA® fabrics are ten times stronger than cotton fabrics, three times than polyester and twice than nylon. Our products apply to CORDURA® fabrics UV coating on both side with silicon so they are top quality and world class.
Cuben fiber made by sandwiching Dyneema® is lightweight and highly durable, which is called ‘super fiber’, polyethylene fiber filaments. The specific gravity of Dyneema is 0.97(floats on water) and Dyneema is stronger than Nylon 6,6 or Kevlar. Cuben fiber weighs only 11.4 gsm, five times lighter than normal lightweight fiber.
Carbon fiber is stronger than AL7001 compared to its weight. Depending on the weight, AL 7001 is stronger but carbon poles are stronger when the patterns of layers are applied. At ZEROGRAM, we applied different patterns of carbon fiber sheet(Cross pattern, longitudinal pattern and diagonal pattern) to our trekking poles to increase strength.
Titanium is a chemical element with symbol Ti and atomic number 22. It is a lustrous transition metal with a silver color, low density and high strength. It is highly resistant to corrosion in sea water, aqua regia and chlorine. We make all cookware with Titanium, because it is durable and safe to human as well as lightweight material.
As the world’s largest zipper/zip manufacturer, in Japan, YKK Group was established in 1934. At ZEROGRAM, all the zippers used in our products are made by YKK Korea Co. Ltd and some extra special zippers are made by YKK Group in Japan.
At ZEROGRAM, all our feather sleeping bags are baffle construction applied to Insotect’s Vertical Thermal Channels (VTC’s) and have more than 850FP with INSOTECT Flow™’s insulation technology. Vertical baffle construction allows the gear design to more closely reflect the contours of the user, taking on a more comfort forming shape which in turn keeps insulated comfort closer to the body. FlowGates™- Special gates make inside feather chamber warm throughout effectively and keep the feathers comfort in the baffles.
To keep ZEROGRAM the world’s most productive, we handle even a piece of subsidiary materials. ITW Nexus is one of the leading companies innovating buckle design and product application. ITW Nexus plastic buckles are used for U.S. military due to their high-strength and high impact resistance. At ZEROGRAM’s products, we use all of our high-strength buckles from ITW Nexus.
Comfort and innovation are as intertwined as the fibers in PRIMALOFT® insulation. Together, they make it possible to fully “Feel the Performance™” in any climate, in any condition. Originally developed to serve the needs of the U.S. Army, who desired a water resistant, synthetic alternative to goose down, PrimaLoft, Inc. is recognized globally as the proven leader and constant pioneer of innovative comfort solutions. All of Never Mind sleeping bags apply to PRIMALOFT® insulation.
At ZEROGRAM, we don’t believe that the best equipment is just made by combining high-tech materials with high-end subsidiary materials. We can not guarantee that the best equipment is made with that combination. After all, it is possible to produce best equipment with standing the test of time. In the process, we always care about human life. We develop the equipment with a sense of guilt about the Earth but it also means that we always care about human life.
