Why is my size sold out?

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.

Reviews

The Best!

"These are undoubtedly the best under garments I’ve ever owned! I now have 5 pairs and would love a few more plus some more socks. They are also superb"

— Avis P. (5/5)

Women’s natural bikini

"If you’ve been wearing these for a few years as I have, you’ll find the cut noticeably smaller. I’m really disappointed as these are all I wear. It’s doubtful that sizing up would satisfy."

— Laura K. (2/5)

Love love love

"I have worn these for twenty years, they feel terrific and fit well. Had to stock up as the rehab I was at ‘lost’ some."

— Kathryn A. (5/5)

Great quality

"I have 10+ year old ibex underwear that’s finally starting to wear out. These fit a bit different but I like them just as much. I can wear a small or medium but prefer the small (I liked the medium better in my old ones). Hopefully they will last as long. Please offer more light colors. The old gray ones were perfect."

— Staci S. (5/5)

Underwear

"Very comfortable and breathable got multiple pairs"

— Courtney B. (5/5)

I only have 10

"I’ve had these for years & and obviously because I have so many I love them. They’re very lasting they feel genuinely comfortable. I do wish that Ibex clothes were still made in the United States as they were years ago. I’m a very old customer and I have many Ibex clothing."

— Manda H. (4/5)

Comfortable, performing Merino Fabric

"I’m all about Ibex and own many different garments, all of which I sincerely love! These underpants not so much. They are made well, comfortable, and quality made like all of Ibex’s clothing. The wool is light and smooth and barely there. Why don’t I “love” them? They are much skimpier than depicted in the stand alone photo. I did order up one size to begin with for comfort, but it’s the cut that is hanging me up. The crotch is narrower, the sides narrower, and the butt is narrower than what I expected, or envisioned from the one photo of them laid flat, not on a model. I’m a size small in practically everything at 5’4, 113lbs, 27 waist and 36 hip. Still giving these 5 stars, because they are a quality item, and otherwise comfortable and functional at keeping you “swamp butt” free while working out."

— Suzanne C. (5/5)

my favorite underpants

"great for travel, great for adventure, great for everyday. The perfect weight, comfortable and easy to hand wash while holding up in a washing machine. I've had one pair for almost 5 years and they are still my favorite."

— Jules (5/5)

Disappointed.

"Very frustrated actually. In the past, the medium was a bit roomy( I still have a pair) Now they run much smaller with less fabric over the cheek area. Can’t wear them and sent them back but they appear lost in the mail, perhaps due to the snow. Last seen 2/5"

— Evelyn V. (5/5)

Needs a bit more coverage

"Great but needs more coverage"

— Gabriela P. (4/5)
