When you purchase a Backside product, you can rest easy knowing you're getting an excellent value, with a superior product. Their Diamond Ripstop is extremely durable, light, breathable, and very wind and waterproof. The poles they use are made out of aircraft-aluminum, which makes them both very strong, and very lightweight. The floors are waterproof bucket-style 4000 PU, with taped seams. They are also made with a thicker nylon than most, for increased longevity and wear & tear. This tent is designed to handle any weather conditions you could encounter in the three seasons it's designed for. It could almost be a four season. Like all of their products, they use all YKK zippers, simply because they're the best.
