Reviews

Nice but don't last

"I purchased a pair in January 2026, and less than a year later (9 months later, in fact, and half of that was summer), they have developed a large run in them. The fit is comfortable, but I guess they're so thin that they just don't last? I launder them carefully and air dry them, so that's not the issue. Disappointing: I had a pair of similar weight Smartwool bottoms that lasted 20 years before they had the same problem. Wanted to love the Ibex, but they just don't last long enough to justify the price."

The best leggings

"Lightweight merino is the perfect legging material. I wear them under ski pants and under skirts for work. Must have more."

— Heather P. (5/5)

Amazing baselayer

"Best base layer I’ve ever used, I stay warm, dry, and cool when you need them to be. And I love the striped pattern. I hope they make more of these. They get looser as you wear them for two or three days, but bounce right back after a wash, looking forward to buying more."

— Valerie M. (5/5)

Not durable

"Unfortunately, these didn’t hold up to regular use as a ski/ski touring base later. After 4-5 tours, the fabric began to rip and tear on top of the thighs. Great weight for warm days, but not very durable."

— Alaina (3/5)

No Fly Tights for Men

"These are great no fly tights for men. Durable with great fit. So comfy for everything from gym workouts to trail runs."

— Mark B. (5/5)

Always the best

"these are the perfect temp regulator under pants or skirts/dresses…. and the stripes are cool!"

— Corinna S. (5/5)

"These featherweight leggings are the perfect base layer. They are not bulky at all. I appreciate the high waist & comfortable waistband. Just what I wanted."

— Jennifer (5/5)

Very thin fabric

"Fabric much thinner than expected. I can only wear as a lining under other pants."

— Nancy J. (2/5)

Perfect everyday winter bottoms

"I live in the cold north and I love wearing these under my pants. It is perfect weight for wearing under clothes. I have been disappointed with other brands due to holes (the last two brands I bought both developed holes the first day). I'm glad to find out that these are woven differently. so far no holes and they are very comfortable and warm."

— Patty M. (5/5)

Almost perfect!!

"Got these as a gift and they are so so comfy and a great base layer. I wore them in 25F (im a californian so that’s freezing for us lol) and it did the job perfectly! Rating four stars though because im 5’2 100lbs and was ordered an xs yet theyre still loose on me in the crotch and the knee area. The length is PERFECT though which isn’t typical for me lol. Overall I do really like these and will still be ordering more since im using them as a base rather than an actual legging."
