Get ready for the best winter sledding of your life! This FUNBOY snow tube isn't your average inflatable - that double layer base makes it seriously durable and gives you a flat bottom for super smooth downhill rides. Made from heavy-duty K80 winter vinyl that's specifically designed to handle freezing temperatures without getting brittle or cracking. At 46 inches deflated, it's the perfect size for both kids and adults (holds up to 250 lbs, so most grown-ups can join the fun too!). The dual handles give you something solid to grip while you're flying down the hill, and inflation/deflation is quick and easy. Oh, and we put every single tube through a 24-hour air test to make sure it stays inflated all day long. FUNBOY is actually a family-owned US company based in Los Angeles, with real customer support you can actually talk to. Whether you're building a sledding hill in your backyard or hitting the local tubing park, this tube is built to last through seasons of winter fun.
