I purchased this and have used it on two hiking trips. Very soft against my skin, and kept me warm. I’ve washed it in the machine washer and laid it flat to dry. Holding up well.

My husband - wore these for days on a 5 day hike in Georgia. Loved the temperature management and no smell! Really high quality clothing. Couldn’t be happier with these.

Love these 'base' pants. The warmth to weight ratio is amazing.I have a 260 weight top as well. The pants & top are my winter go to base layers.

I have to ware them most of the time, because I have damage nerve from my spine to my right legMy right leg is more sensitive to the cool or cold air , so I cut the left leg of them of, to balance both leg the sameI have tried them all ,but have to say they are the best and you hardly notice you have them on
Needed long Johns, first scoffed at the idea of no peepee hole, but thought about how I never use it, plus I could have a matching outfit with my wife. You get all the benefits of merino wool while leading a revival of men in tights.
Fine laying of good quality. Is sufficiently warm for walks when it is below zero degrees. Fit is as expected, is not bigger / smaller. After you have had the laying on for a while, it may be that the fabric is looser, but not very much.
I needed a light weight bottom baselayer and these 200 Oasis Legging fit the bill. I have several other merino wool products from Icebreaker and they have all been quality products. These were no exception. I am 5'9", 162#, with a 32" waist. The medium is a perfect fit. Although it is stretchy, if you have extremely thic thighs, this may not be the leggings for you. The fabric has a great weave and feels soft against the skin, which is what you want in a baselayer. I've primarily used these leggings as my campwear during backpacking. It also sleep in it and it ads warmth to my sleep system. I'm looking forward to many more nights in them
Extremely comfortable and warm leggins. Provides adequate warmth when outdoors during cold winter days in Finland. The most comfortable baselayer I've ever worn, well worth the money. Fits true to size.
These are a must have for me when the temps drop. Have a few pair, including some 260s.Durable, well made, no complaints about quality.
- best baseline for trekking and hiking in my opinion- the best price for great quality product here on tradeinn
