Care

Wash: Pop your Woolly in the machine on a cold cycle with similar colors. But be careful—fine merino fibers can snag on zippers, buckles, and Velcro. Avoid washing with jeans, jackets, backpacks, or any harsh fabrics.

Dry: Tumble dry on low or go au naturel and hang it up to dry.

Avoid Bleach: Skip the bleach—it’s not a friend to wool fibers.

No Iron Needed

Pilling: Wool may pill over time, but turning your garments inside out before washing can help slow this down.

Air Dry Option: For the air dry lovers out there, lay your wet Woolly on a towel, roll it up like a burrito to gently squeeze out extra moisture, then hang it up for a breezy air dry!

Reviews Summary
Customers say these boxer briefs are exceptionally comfortable and soft, with many praising the fit and breathability for everyday wear and active pursuits. The merino wool material keeps them dry and fresh-feeling, resisting odor even during intense workouts or multi-day trips. Reviewers appreciate the longer inseam options that prevent riding up and chafing. Common feedback addresses the waistband, with some finding it rolls or feels restrictive, while others note the horizontal fly design takes adjustment. A few mention durability concerns with holes appearing after limited wear, though many report the briefs holding up well. Overall, customers find these a worthwhile investment for comfort and performance.

    If you are debating between these MerinoAire Longdrop vs normal MerinoAire boxers, definitely go with the Longdrop. the extra 3" is very much worth it. They work very well for working out and are extremely comfortable! will definitely be ordering more.

    I cant tell any difference between the active and regular boxer briefs, but they are equally fantastic. I dont even want to wear any other material as a brief anymore. 10/10

    Don’t think just buy

    The most comfortable underwear anyone has ever worn. Moisture wicking and heat regulating in ways you wouldn’t believe.
