Icebreaker  260 Merino Tech Thermal Leggings with Fly - Men's

Needed some long underwear that would last & keep me warm. I work outside in the elements & Icebreaker had not only the highest rating, but also the most expensive. In the beginning they fit great & seemed like the obvious winner. Unfortunately, had them for less than a 5 months and the crotch completely fell apart. The material just did not last at all with the work load I have on a daily basis. Would not recommend to a friend.

I bought these for some winter hunting/camping, and so far I'm very pleased. I've had some Merino that feel scratchy, these are smooth as silk. They held up to a 3 day hunt, logging somewhere around 25 miles in tough terrain as a base layer, and I'm well pleased with them.

These were my daily underlayer when I wasn’t working. They regulate body temp very well and I only think I washed them three times during the season. This was only due to spilling food on them. I work and play at a resort. I didn’t wear these for work due to the chance of diesel, hydraulic fluid or a slew of undesired chemicals soaking in. They would definitely get the job done though. If I wasn’t working these were on. I got a pair for work next year, black ;) Also wore the matching top and can’t recommend enough. I’m sure I’ll get another season if not more.

I gave these to my boyfriend for a gift. He works in the Northern Sahara in the winter, which is bitter cold, especially at night. He can layer these easily and reports they really help him stay warm.

Used these last night camping at Chatfield Park outside Denver. Got down to nearly freezing, but legs stayed toasty. Super comfortable.

Bought my first pair in 2014 and they held up for years even though they were out through the wringer. Keep buying them and still the same great quality as before. I love the fit of these, tried smart wool, rei and others but the fit was never just right. These always fit perfect! I love the feeling both in active multi-day mountaineering climbs and also just chilling around camp relaxing staying warm and comfy. Back to the active part… the benefits of merino are magnificent and now only wear it for my under-layers in outings. The lack of smell is always great when sharing tents with others who have been on a trek for a few days is always magnificent. The capacity to keep you warm even on those sweaty push to the top days has me forever grateful. Did I mention the fit!! Hahaha Love these! The price is definitely worth it. Go ahead and treat yourself you won’t regret it.

Not as warm as the Lapasa that I have very disappointing

Icebreaker is "top of the line". I have tried all of them and at this point I think icebreaker Merino is the best with the most choices for cold weather variations . I buy a variety of thermal ratings and layer them as temperature variations may require during an outing. Looks great, feels great. works great ! See you this winter on the slopes !

I purchased the Icebreaker Men's 260 Tech Base Layer Leggings for my husband. I also purchased the Base Layer Top. He like both the top and leggings very much. It is difficult to find a good fit for him anywhere. He is tall with an athletic build. Unfortunately, I had to return both pieces. We will keep trying.

I purchased these leggings more as traditional thermals. They fit well and seem to be of good quality. I have not had the opportunity to test in cold weather hence only 4 stars, but am pleased with how they look and feel. As the website states they do appear to run slightly on the large side.
