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 merino wool boxer briefs are exceptionally comfortable and provide excellent moisture-wicking properties. Many appreciate the longer length that prevents chafing and riding up during activities. Users frequently praise the breathable fabric and odor resistance, with some noting they can wear them for multiple days without washing. The fit is generally well-received, though some mention the waistband can roll or feel restrictive. Common concerns include durability issues, with several customers reporting holes developing within months of use. The horizontal fly design receives mixed feedback, with some finding it awkward or prone to unwanted exposure. Despite durability concerns, most customers find them superior to synthetic alternatives for athletic activities and daily wear.

    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.

    These are the best merino boxers I’ve found! Woolly has been tinkering with their MerinoAire line, and i feel this is the best design yet. Would be five stars if not for the price, but definitely top-of-the-line in quality and comfort!
