Pretty Good
December 19, 2011

This is my first boxer-brief wool underwear, previously owning only cotton and polyester blends. The wool is definitely warmer. I just ran outside yesterday morning at 25 degrees and wear my legs were previously cold to the touch upon my return, warmer with these. They probably work best with layering (like everything else). That being said, I could probably wear these as everyday underwear, they are pretty comfortable. Some have written that this runs smaller, but I think they've run true to size. I've got thick legs and rear, and didn't run into any issues. I'm not quite sure if the front wind flap really provides more warmth than without one (I don't own the other). As far as durability, I'll have to give it more time, only had them a short while. Summary - good wool underwear, if not a bit pricey.

Pros: Build quality, Performance, warm, Cons: Cost
