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.

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.

"Great jacket. Nice fit, stretchy which I like. A little lighter than I had hoped but I'm okay with it. I recommend it for hiking and backpacking."

"it's soft, warm and the pockets are great. I orgered the Men's version mostly because a couple of reviewers said that the men's jacket had more pockets. Glad I did! make it excellent to travel in."

"Have purchased many (4) of these over the years and this one may be my favorite. Classic design stylish enough to keep you toasty while wearing under a sports coat while functional enough to layer in the back country. One of my favorite layers year round!"

"Just came back from a week in late fall Berlin with this. More and more, I prefer merino wool to even the best artificial fabric blends. This is a really nice manifestation of merino. It is not bulky and hangs nicely. Like the two internal pouches, besides the three pockets, which can be utilized to stash a magazine or hat in. I was drawn to the yellow for a splash of color instead of my more usual black or gray tones. The only complaint is that the collar is just a bit too high without having the structure to keep it from flopping a bit. Fine when it is zipped up but when open it can’t seem to decide if it wants to flop or stand tall. This is a purely aesthetic issue, not functional. The sleeve diameter is the right size to not look too large but still able to slide up your arm and stay there when it is a bit too warm. And they make a matching color hat! As with all Ibex, it is pricey, but I thgiunk worth it."

"25% heavier than the Shak Lite and with an added zipper pocket. Very nice for walking the dog on a cool morning. My wife saw how much I love and wear my Shak Lite, she got me this one for my BD this year."
