Reviews

Every pair of thermal bottoms

"Every pair of thermal bottoms I’ve bought from Icebreaker develops random holes in the seat, crotch, and thighs. I’m not a large guy, nor overweight. I love the feel of the product but unless the weave quality can be markedly improved, I’m not interested. Especially at this price point."

"Superb quality and fit! I love them!"

Geoffrey U. (5/5)

This is my 5th and 6th pair of 260 leggings

"Working as a x/country ski trail groomer, icebreakers are the only product that meet my requirements. As a base layer, under my Carhart bibs, they breath, wick and stays warm under demanding conditions."

Chief T. (5/5)

I am a woman who prefers mens wool legging to women's versio

"Love these. I have wide hips and a waist and always find that women's leggings don't fit me. This is true for not just Icebreaker, also other companies, but for some reason women's leggings often don't have a gusset so perfectly good leggings become unwearable because the crotch rips and frays. . . so I buy mens leggings."

Merino 260 Tech Thermal Leggings w/ Fly

"The Icebreaker Merino 260 Tech Thermal Leggings w/ Fly are an exceptional cold-weather base layer that delivers warmth, comfort, and breathability. If you're looking for reliable winter leggings for outdoor activities, these are a solid choice. These leggings are a game-changer for winter layering—warm, breathable, and super comfortable. Whether for outdoor adventures or just staying cozy, they perform incredibly well. Highly recommend!"

JG (5/5)

Comfy …. Cozy … great fit

"Took skiing and despite the huge fluctuation in temperature (30 deg in the morning and 70 deg in the afternoon) it remained comfortable"

Mongo (5/5)

For keeping warm overnight

"I work third shift, 9p to 6a, and it gets very cold walking the lot. These base layers cut the night wind and keep me warm under my regular uniform."

Tone (5/5)

Base layer

"My first base layer from ice breaker. It's perfect for east coast snowboarding since it usually doesn't get super cold here. I was able to use this (plus the matching top) under my jacket and snow pants and didn't need much else unless it got pretty cold."

Stephen (5/5)

Magnifique! C'est doux, c'est chaud, c'est ajuster!

"La meilleure couche de base de tous les temps! En plus d'être beau et stylé, il est extrêmement chaud. Ça fait 25 ans que je suis coach en snow au Québec, dans des températures qui peuvent descendre dans les -30, -40 avec le vent. Si j'avais connu icebreaker plus tôt, je ne me serais pas gelé avec des couches et des couches qui finalement ne me tenait jamais au chauf. La dernière semaine il a fait extrêmement froid, et pas un instant je ressenti le froid grâce cette couche de base 260 en pure Merino. J'adore ! Merci à Icebreaker pour enfin nous procurer un vêtement aussi chaud et technologique pour nos sports d'hiver."
