Why We Like The Alpine Onset Bottom
We love the natural breathability and odor resistance of wool, which is why we're choosing the Alpine Onset Bottoms for our cold-weather endeavors.

Basic but high quality product.
The leggings are the perfect base layer for all your cold weather activities. I’ve used them snowboarding, climbing, backpacking, and jogging. 150 is just the right amount of warmth that doesn’t cause you to overheat while exerting yourself. My only suggestion would be to incorporate tall/ short sizing rather than just XS to XL. As so someone with a very skinny waist I had to go with the small size, which rides up significantly as I’m 6,2ft. Not a big deal as I always wear these with long socks.

Dye transfer problem
Functionally, these perform well as a lightweight base layer. However, even after three washes they continue to transfer dark-colored dye to my legs every time I wear them. Hard to recommend these as a result since they are meant to be worn next to skin.

Another Stellar Item
These are very very well anatomically mapped leggings that fit very comfortably. Once again OR has outdone itself in the realm of outdoor clothing, this time in merino baselayers that I would argue are better quality than some of the brands that are known for making nothing but.

Excellent
Excellent comfort and performance. I deliberately wore the whole set in warmer and colder environments than it's made for, no issues. Be mindful when it's new the Red color way puts off a lot of red fuzz.

Lightweight, warm, and comfortable
Merino wool is the way to go! This is a great base layer for cold weather. The sizing is true-to-size, the fabric is a lightweight insulating layer, and the benefits of merino wool mean that there is not bad odor. I highly recommend!

Very comfortable for bigger man
I am 6'3", 235, and these are very comfortable. They feel almost athletic like. Sometimes I'll even wear them to bed normally.
