Puma and Cara Delevingne, the English model and actress, have co-created Exhale, a new eco-conscious yoga collection. The new line is said to use at least 70 percent recycled polyester, and to fully offset any unavoidable carbon emissions. The Exhale collection comprises a high-waist full tight, studio bras, a knit cover-up, a crop top, a boyfriend-inspired tee, a leotard and a jogger. All the items are offered in a neutral color palette. The collection was launched by Puma worldwide on Feb. 15.
