All the cooling power of our Made-in-the-Jade™ technology combined with a seamless silhouette: introducing Armachillo® Seamless Briefs. Soft, silky fabric is knitted in the round to conform to your shape with as few seams as possible. And just like the rest of our Armachillo Unders, these are packed with other Duluth-y details like an odor-fighting finish, flatline stitching to squelch chafing and a pinch-free waistband. Seriously, you’ve got to feel ’em to believe it – try a pair for yourself today!
