Why We Like The Merino 150 Boxer

Super breathable underwear is one of our necessities when we're out adventuring, and that's why we're turning to the Merino 150 Boxer. It's constructed from a merino 150 blend fabric with the result being a light and stretchy boxer that's ideal for everyday and active wear. Merino wool wicks moisture and resists odors so we can stay fresh all day.

Nothing gets between me and my Smartwool merino boxers!

[This review was collected as part of a promotion.] Have been wearing Smartwool merino boxers for several years, so I've bought this product again and again. They're my everyday go to no matter what season we're in. Keeps me cool in the Summer and warm and cozy in the Winter. Wouldn't have anything else between me and my chinos! Don't tell my wife I said that!

Great boxer made even better

Familiarity:
I've put it through the wringer

Great boxer. I love the improved waistband. Very thick but merino lined and never folds like so many bands do regardless of activity.

Most comfortable underwear I've ever worn!

I bought enough to wear every day. The most comfortable boxers I've ever bought. They are expensive for underwear, but with the wool/nylon blend I'm hoping they'll last long enough to be a good buy!
