Lark Bamboo Pajamas 3 month baby gender neutral white and teal with bright rainbow arches zip up footie pjs upf. Our exclusive Softek™ bamboo is buttery soft, wicks-moisture away from delicate skin, regulates temperature and can withstand everyday life. It's no sweat. Really. We worked with a textile mill to create a proprietary natural wicking fabric that keeps babies and kids dry, comfortable, and safe day and night. Our goal was to stay away from the polyester and chemically finished fabrics. Our fabric is a bamboo cotton blend that uses a special capillary thread that pulls moisture away from your child's skin. The result: a super soft fabric that is hypoallergenic, durable and unlike most bamboo blends, can go in the dryer! Sleep safe. Play free. Our exclusive Softek™ bamboo blend is Oeko-tex 100 Certified, so its tested for over 100 different chemicals to ensure its safe for delicate skin. Bamboo is naturally UPF 50+ Sun Safe so your child is protected without additional chemicals.
