Great start to keeping your lower body warm
These are great for layering in cold weather. I can't tolerate being cold, so I wear them all the time!

Get them, but take extra care!
Love them and wanted them for quite some time! Could never justify the price, until winter hunting season. I like how thin, flexible, and warm they are. After my first wash (on cold & delicate) I noticed several holes along the outside leg. This was quite a let down given the wait and price.. I cannot say if I rubbed up against something, & if I did, they were used as an under layer. So not too sure what happened. I could see myself getting another pair as I love pretty much all smartwool products. The warmth and comfort are top notch.
