MELBOURNE BESTIES SWEAR YOU CAN WEAR THSE GYM FOR DAYS WITHOUT WASHING

CLIENT: LOCIONNE

OUTLET: 9HONEY MONEY

Michelle Huang and Elle Castellani have developed gym tights they claim you can wear for days on end without washing because of the special ingredient: collagen.

"We never actually thought we should make leggings with collagen extracted from marine life," Castellani tells 9Honey of the new fabric used in their brand Locionne's Genesis collection.

She and Huang were intrigued when they came across bionic nylon, a groundbreaking textile technology that is marine-collagen-infused textile.
