I've worn these on a 16 hour drive, a 12 mile hike into the rockies and picking up hay bales on 95 degree days. These are hands down the most comfortable I've ever worn. I wish we would have had these in Iraq! I've already ordered more.

These are top tier. If you have worries that wool underwear will be itcy or scratchy, that is not true with these. They are extremely soft with all the seams folded in so there is not irritation there either. The odor control is also fantastic. You can def wear these for multiple days if needed and they will not stink. Great produce. Wool is incredible.

Bought my boyfriend a pack to try as well. They are his favorite!

I tried one and just bought three more (the three-pack) in spite of not really needing more underwear right now. So I clearly like them.

I switched from cotton to synthetic because I needed breathability and sweat control for my time in the navy. Not only is wool more comfortable but it controls sweat better and is more comfortable in heat and cold. A 100% upgrade for wear in any environment and temperature. Now for the slow and controlled transition to all wool!
