No stone unturned

Unlike some outdoor clothing brands, we don't buy our fabrics - we make them.  It takes years to develop and perfect each fabric until it is production ready.  To achieve the performance and comfort we seek, we continue to control each and every step in the process starting from the raw wool.

We buy the wool ourselves from Tibetan communities to ensure its origin and quality, and we develop our fabrics and our clothing using the same fanatical attention to detail.  Each new fabric undergoes extensive laboratory testing and long term wear trials with our team of mountain athletes.

Mountain tested

Our Adventurers team is comprised of outdoor professionals.  These men and women are particular about the kit they choose to take with them. They test our apparel in real world conditions: ski-touring in Arctic Greenland, trekking across the ChangThang plateau and climbing in Chilean Patagonia.

Our fabrics are tested for countless other real world settings: on the long-haul journeys to distant locations, and on thousands of cumulative hours of training runs, hikes, rides and skis.

Hima-Layer Original 230 vs. Merino

According to the tests carried out in independent laboratories, this fabric is weight-for-weight:

40% warmer 66% more breathable 17% faster at transporting water vapour away from the skin

Just like merino, it’s naturally odour-resistant, while its softness has been compared to cashmere. While merino sheep live at around 1,000 metres above sea level, yaks live in a more challenging environment. They endure hail, ice, wind and rain at 5000 - 6000 metres altitude.

Active-Use Testing

A study by Sheffield Hallam University’s Centre for Sport & Exercise Science has shown that when exercising in low temperatures, base layers made with Hima-Layer™ Original 230 maintain core body temperature better than synthetic or merino base layers. During the test, researchers measured the surface temperature of the test subjects' skin to see how much heat they were losing while running. The test subjects who wore yak wool lost an average of just -3.5˚C, compared to a -6˚C drop when wearing merino and -8˚C when wearing polyester.

The less energy you burn to stay warm, the more you can dedicate to movement. So if you plan to exercise in cold conditions, kora base layers are your best choice.

The yak wool’s warmth and ability to endure day-after-day wear with fluctuating temperatures makes it a must. It also remains a fabric that is my base layer on most days just ‘living’ here in Shangri-La.
