Justa Tube is so much more than an ordinary pool tube. This black donut tube is hypoallergenic, meaning it's much safer for those prone to allergies and irritation. The Schrader valve stem is shorter than a standard auto valve and has a tapered cap, so there's no discomfort or scratching legs. Justa Tube Pool Float provides year-round fun! In winter, use it to sled down hills of snow. In summer, you'll enjoy this inflatable black tube at the pool, river, lake, or ocean!
