This Mont Tent has a 25,000mm waterhead Nylon floor for superior protection in wet weather. Many competitor tents have only a 5000mm waterhead and some as low as 1200mm! With waterhead ratings as low as these, the pressure of you sitting in your tent can cause water to soak through from the wet ground!
Most tents on the market use Poly-Urethane (PU) coating to waterproof their tent floors. This Mont tent uses Thermoplastic-Poly-Urethane (TPU) Lamination which is a far superior form of waterproofing. TPU is more durable, more resistant to chemical damage (sunscreen, oils, insect repellent etc), and is almost impervious to hydrolysis. Hydrolysis results in a permanent and irreparable de-lamination between the PU and the Nylon fabric; the floor is no longer waterproof. Laminated TPU floors are lighter, more waterproof and more durable than Coated PU floors.
