The FUNBOY Snow Tube is the perfect downhill snow tube for backyard snow play for the whole family this winter. This is a commercial quality snow tube that works just as great as it looks! Featuring a reinforced dual-layer base design, we've created a strong and durable snow tube that features a flat base for smooth downhill sledding. The oversized 46'' (deflated) diameter is big enough for the largest adults and holds up to 250 pounds. Specially formulated K80 snow vinyl withstands cold winter temps.
