Making clothing can be a dirty business, but we strive to keep it clean. Our line is crafted for quality and long-term performance. And we limit what we make: small-batch production ensures every garment is built to the highest standards and finds a loving home. Our approach minimizes landfill waste and uses less energy and water. We know it’s disappointing when a style you love is out of stock, but we appreciate your joining us in our pursuit of the highest environmental standards and carbon neutral impact.

Micron gauge: 19.5μm
Part mid layer, part outer layer, our Ponti is 100% merino wool, double-knit for incredible insulation. The interlocking structure monopolizes on merino’s natural elasticity, allowing it to move with you while skinning up the north side of the mountain or reaching for that final arête. Merino Ponti is our fabric of choice for the Shak collection, named for the iconic Antarctic explorer Sir Ernest Shackleton. It’s ready for any and every expedition you find yourself on.
Traditionally, the end of a season is defined by the quarterly transition of sunlight caused by the Earth's tilt and its annual revolution around the sun. These seasonal transitions bring many opportunities for change.

"The insulation characteristics and density of the fabric are superb. I selected true to size on the fit because sleeves and chest are great for my 5’10” frame, average build and weight. However the jacket is quite long, ideally fitted to a much taller person. The large might be ideal for someone of lean build who is 6’2”. If the length fit me better, I would call this jacket perfect."

"Definitely worth the price."

"Bought this and the indie hoodie for a “pick one” gift. He liked both so much that we have to keep them both. Great quality and weight, the green is an awesome color too."

"Like the jacket but was surprised the ibex logo was nowhere to be found. I have some older Ibex tops and they all had them"
— Tony L. (4/5)
"I'm 5'10", 165 lbs. The medium is the perfect fitting midlayer for hiking, skiing, trekking. I'm now on my second Shak jacket. The first one I had for nearly 20 years and wore it until it was, literally, just threads. It traveled with me to 4 continents, innumerable mountain tops, and even a few unplanned biffs in mountain streams."
