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.

Reviews

Had me covered

"Two weeks in Japan during shoulder season - cool mornings, warm/hot afternoons, rainy cool day, it made little difference. The wool, the long sleeves, all kept me comfortable. And packs in almost no space."

— Tom B. (5/5)

Comfortable, Functional and Looks Good

"I got the Naturalist for travel, to both look nice and serve the great function that wool does and I am not disappointed. I am saying "runs small" because I am lean and only 5'10" and the Large is a better fit for me. I have somewhat broad shoulders and some muscle so if you are like me, you're going to want to size up where Ibex will suggest medium."

— Jason J. (5/5)

Another win

"Great color, perfect fit, great quality, no itchy tags; it's merino; what more is there to say!"

— Jeanette Z. (5/5)

Not as I expected

"I have many IBEX products. This item I thought would be like the old Zephyr, heavier weight. I was wrong this is a lightweight item. If that is what you are looking for than this is it. If you wanted something with a more substance this is not for you"

— Stephen E. (5/5)

Long sleeve crew

"Long sleeve crew fits just right."

Honestly, the premium quality of

"Honestly, the premium quality of these shirts keeps getting better. I've been wearing ibex shirts for everyday wear, and pajamas, for years and this material just seems to be getting nicer and nicer every time I buy a new one. I absolutely love this light blue color as well. A perfect addition to my wardrobe."

— Michael H. (5/5)

"Sizing is off. It fits large for its size. I always wear medium, but this shirt feels so big."

— Bartosz (3/5)
