Solly Wraps are made of lightweight, buttery-soft, and eco-friendly TENCEL™ Modal fabric that has just enough natural stretch to help achieve a snug, secure fit. This breathable fabric will keep you both cool and comfy all year round, even in warm summer months. Made from the pulp of sustainably-harvested Austrian beechwood trees, our Solly Wrap carrier is naturally soft—up to twice as soft as cotton!
