I love Patagonia- cool company, cool clothes.
But their "Change Your Underwear for Good" program just sounds weird to me:
"For the past 20 years, Patagonia Capilene(R) base layers have
accompanied hundreds of thousands of outdoor enthusiasts on countless
adventures. When your garment has made its last trip, give it back to
us. Through the ECOCIRCLE(TM) fiber-to-fiber recycling system, your
old favorite will be turned into fiber for new garments."
I guess it makes sense, but the thought of some guy's ratty old underwear becoming my underwear is not particularly attractive...
You can learn more about this program here.
