I was pretty excited to get this warm piece of Merino Wool. They fit great, are warm and breath well. Only disappointment was after 3 treestand bow hunts the stitching gave out on the back. I ended up sewing it, so it's fine now. However, I didn't expect something to rip as a base layer for this kind of $. Other than that great product and much better than other base layers.

Only base-layer you’ll need once the cold hits

Well made and very warm. Generally, I pull these out when it gets in the 20 or below. They can be too warm if you are active in 30 degrees, sitting they are nice however. Best wool that I have used.

Best base layer pants I've ever worn. All the guys I hunt with got a pair after I talked them up. Warm, Lightweight, no smell, and comfortable through all types of movement. From tree stand hunting to stalking.

I hesitated to get smalls, but am glad I did. Mediums would have been too loose with my skinny legs & butt. Wore them under insulated pants in cold and wind, and under waxed cotton in cold and rain. They will also make good under-wader pants when the water is not too cold. They are warmer than another outfitter’s “expedition weight.” Very happy with purchase.If you made a heavier “Blast Furnace” I’d get them too.
