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!
One Year Guarantee
People who make the move to merino typically don't go back. We're so confident that our underwear is the best around that we'll back them for a full year. We want you to be happy! If for any reason your Woolly undies aren't top notch we'll replace them.
No fuss just comfy butts.
