GUESSED IT, MUSHROOMS, WHICH YOU PROBABLY HAVE IN YOUR OWN BACKYARD. HERES MORE. THINK ABOUT THE WORLD OF HIGH FASHION, THE RUNWAYS OF NEW YORK, PARIS, AND MILAN. THE FIRST THING THAT COMES TO MIND PROBABLY ISNT MUSHROOMS. BUT THE HUMBLE FUNGI IS TAKING FASHION BY STORM. LULULEMON, EVEN FANCY FRENCH BRANDS LIKE HERMES ARE EXPERIMENTING WITH A NEW FORM OF VEGAN LEATHER MADE FROM MUSHROOMS. >> IF YOU THINK ABOUT LEATHER, ITS ABOUT A TWO TO THREE YEAR PROCESS FROM END-TO-END, FROM A COW BEING BORN TO A PRODUCT BEING MADE. WITH MILO, ITS ABOUT EIGHT WEEKS. >> Reporter: AT BOLT THREADS IN CALIFORNIA, THEYRE USING THE FIBROUS ROOT STRUCTURE OF MUSHROOMS TO CREATE ANIMAL-FREE LEATHER CALLED MILO. >> PUSHING 5,000 FAILED EXPERIMENTS AT THIS POINT, BUT WE EVENTUALLY FOUND A WAY TO MAKE SOMETHING THAT HAS THE SOFT, SUPPLE, DURABLE FEEL OF LEATHER, AND REALLY IS GOING TO DELIGHT CUSTOMERS AND DESIGNERS. >> Reporter: THE MUSHROOMS ARE GROWN IN THE DARK IN GIANT BAGS OF SAW DUST, AND GO FROM SPORES TO SHROOMS IN ABOUT A WEEK. THEN THEYRE TWRANSRANSFORMED IN FABRIC USING GREEN CHEMISTRY PRINCIPLES. THE RESULT, ENOUGH TO IMPRESS “VOGUES” SUSTAINABILITY EDITOR, EMILY CHAN. >> ITS THE CLOSEST MATERIAL WEVE SEEN TO LEPREPLICATE THE LUXURIOUS FEEL OF LEATHER. >> Reporter: THATS GOOD NEWS. MUSHROOMS, UNLIKE, SAY, COWS, ARE EASY TO GROW. THEYRE NATURES RECYCLERS, FEEDING OFF DECAY, AND NEED FEW RESOURCES TO THRIVE. MUSHROOMS ARE EVERYWHERE YOU LOOK IN NATURE. THEY THRIVE IN SOME OF THE MOST INHOSPITABLE PLACES. THE IDEA BEHIND SOMETHING LIKE MILO LEATHER IS TO TAKE THIS AND TURN IT INTO A PRODUCT THAT LOOK LIKE, FEELS, AND, FRANKLY, SMELLS A LOT LIKE REGULAR LEATHER. ADIDAS IS REMAKING THEIR ICONIC SNEAKER IN MILO LEATHER. >> IF IM BUYING USE, AM I GOING TO NOTICE, WHOA, THIS DOESNT FEEL RIGHT? >> THE MATERIAL IS REALLY SUPPLE TO TOUCH. ITS EXTREMELY DURABLE. ITS BEEN DEVELOPED IN A WAY THAT WILL HAVE SIMILAR LONGEVITY TO LEATHER. >> Reporter: THE MAKER OF THE BURKAN BAG IS MAKING A MILO OPTION. THE REVOLUTION ISNT LIMITED TO MUSHROOMS. COMPANIES AROUND THE GLOBE ARE USING ALGAE, PINEAPPLE, EVEN SPIDER WEBS TO CRAFT THE SUSTAINABLE THREADS OF THE FUTURE. >> AT THE MOMENT, YOU KNOW, AROUND 60% OF OUR TEXTILES ARE MADE OF POLYESTER. THEY ALSO RELEASE REALLY HARMFUL MICROPLASTICS WHEN WASHED INTO THE OCEAN. SO IT IS CRUCIAL WE LOOK AT A MORE SUSTAINABLE WAY OF MAKING OUR CLOTHING. >> Reporter: THAT SAID, BIO FABRICS, INCLUDING MILO, ARE NOT A SILVER BULLET FOR SUSTAINABILITY. WHILE MANY USE FEWER RESOURCES THAN SYNTHETICS, MOST ARENT 100% CARBON NEUTRAL. AND THEYRE JUST ONE PIECE OF A BIGGER PUZZLE. >> ITS REALLY IMPORTANT THAT WE TACKLE THE ROOT CAUSES OF THE PROBLEMS, FOR EXAMPLE, CUTTING CO2 EMISSIONS, TACKLING ISSUES LIKE OVERPRODUCTION, SO ITS NOT THE WHOLE SOLUTION, AND IT CANT BE SEEN AS THE WHOLE SOLUTION. >> Reporter: STILL, BIOFABRICS ARE HAVING A MOMENT, AND AS CONSUMER DEMAND FOR EARTH-FRIENDLY DESIGN INCREASES, MUSHROOMS JUST MIGHT BE THE FUTURE OF FASHION. GUYS, IT IS NOT JUST MUSHROOMS. THERES ACTUALLY A COMPANY THATS MAKING SHIRTS OUT OF ALGAE. THEYRE FULLY COMPOSTABLE AND BIODEGRADABLE BIODEGRADABLE. YOU NEVER HAVE TO THROW THEM AWAY. GUYS? >> OR YOU GET STUCK IN THE RAIN, AND THAT CAN LEAD TO OTHER ISSUES. WHEN WILL SOME OF THESE ITEMS ACTUALLY BE ON THE SHELVES? >> Reporter: SO I ASKED ADIDAS WHEN WE CAN EXPECT TO SEE THE MILO LEATHER SNEAKERS. THEY DIDNT HAVE AN EXACT DATE, BUT THEY SAID PROBABLY BY THE END OF THE YEAR. I ALSO ASKED THEM, IS THIS GOING TO BE A LIMITED RELEASE ITEM THAT HAS A MATCHING PRICE TAG? THEY REASSURED ME THEY WANT THESE SUSTAINABLE PRODUCTS TO BE ACCESSIBLE AND NOT LAUX RYUXURY. HOPEFULLY IT IS SOMETHING WE CAN ALL AFFORD. >> ASIDE FROM BUYING THIS MUSHROOM LEATHER, ANY OTHER TIPS FOR MAKING MORE SUSTAINABLE FASHION CHOICES IN GENERAL? >> Reporter: CRAIG, I AM SO GLAD YOU ASKED THAT. WE WANT TO BE MORE SUSTAINABLE IN OUR PRACTICES. THE BEST THING WE CAN DO IS ACTUALLY BUY LESS. WEAR WHAT YOU HAVE A LITTLE BIT LONGER. WHEN YOURE DONE WITH IT, GIVE IT TO A FRIEND OR RECYCLE IT. BE REALLY CONSCIOUS IN YOUR CHOICES. BUYING A LITTLE LESS IS PROBABLY THE EASIEST THING THAT ALL OF US CAN DO FOR THE ENVIRONMENT. GUYS? >> LESS CONSUMPTION. GOOD ADVICE. >> SARAH, THANK YOU SO MUCH. FASCINATING STORY. ITS LIKE THAT T-SHIRT BLANKET I HAD MADE. INSTEAD OF THROWING THEM OUT AND BUYING A BLANKET, MAKE IT A BLANKET. >> MUSHROOMS, I REMEMBER THOSE
