Sorry, cotton — these “soft as heaven” Bamboo Cool draws may be the only thing you want in your underwear drawer.

Made from bamboo viscose with just a touch of spandex, reviewers call these Bamboo Cool briefs “the most comfortable and breathable boxers I’ve ever worn.” In fact, many say that after trying the 4-pack, they’ve continued to buy these undies, as they now “can’t imagine wearing regular boxers anymore.”

“I thought the [Bamboo Cool] name was a marketing thing, or a figure of speech... but they literally feel cool to the touch. The entire time you’re wearing them,” shopper Micheal wrote, adding, “I’m never wearing the cotton or spandex crap ever again. I’m not joking and that isn’t a hyperbole.”

“I slipped these bad boys on and instantly questioned every life decision I’ve ever made involving cotton,” another joked. “Breathable? Bro… these things are so breathable I swear a light breeze passed through me. I don’t know how, but it felt like Mother Nature herself gently exhaled on my lower half.”

Others tried the briefs after their brand-name favorites got too expensive. “I ordered a 4-pack of these Bamboo briefs at a fraction of the Patagonia price and now have my permanent replacements,” GFF wrote. “These are excellent quality and fit (I am a 32” waist and wear a medium). Highly recommend these.” “These boxer briefs didn’t just change my wardrobe—they changed my worldview,” one joked. “...I am one pair away from achieving inner peace.”
