"Buyer beware!!! Had many pairs over the years. Seemed to go on and on. Now disintegrate in a short period of time! They have changed to cheap supermarket thermals which cost quarter of price."

"Excellent garment as always. But my very next email offered many IB garments including what I bought, @40% off. Learnt about online shopping from that."

"fantastic product keeps me warm on those winter nights"
— Subman (5/5)
"Wonderful across the board and everything proved as advertised. Perfect manufacture excellent fit, I shall soon buy a second pair."
— Clive (5/5)
"I patrol at Winter Park and spend long days in my gear. These leggings are awesome for both cold and temperate days. The 3/4 leg length is good for ski boots and saves me from having excess material on my shins, under the boot tops . I've worn them on the front side and in the back country without over heating. The only design issue that needs to be addressed is the necessity of a fly so you don't have to pull down your pants to relieve yourself."
— WP S. (4/5)
"These 3/4 thermal leggings are perfect for snowboarding and cold-weather activities. The merino wool fabric provides excellent warmth, breathability, and moisture control without feeling bulky. The 3/4 length sits just above my boots, preventing uncomfortable bunching. They fit snugly without restricting movement and stay odor-free even after long sessions. Definitely worth the investment for staying warm and comfortable on the slopes."
— Pierre (5/5)
"Love the 3/4 length These are very comfortable not as warm as 260 so for more intense activities these are perfect Merino is great, stays dry, feels great and doesn't smell"
— Skier (5/5)
"I use these leggings alpine skiing. The 3/4 length is a game changer with ski socks!"
— Luke (5/5)
"The material did not seem to be as robust as that used previously. A ladder appeared in the first week of use"
