Your baby boy will be comfy and cute in our Zoo Time arm sleeves. Whether heading out on an adventure in the stroller, tagging along with siblings or simply charming friends and family at a backyard barbeque, his little arms will be protected from the sun. Our Zoo Time arm sleeves are certified UPF 50+ and made from a 60% polyester/35% cotton jersey/5% spandex (latex-free) fabric blend, which makes them lightweight and breathable. The top of each sleeve is constructed with a thin, non-restrictive elastic band to keep it from slipping. Machine wash cold and tumble dry low or lay flat to dry. Zoo Time is only available in size XS (0- 12 months). Sold in pairs.
