Discovery Series by Hotcore® Adventure TentsDiscovery Series by Hotcore® Adventure TentsAll 3 of Hotcore’s Discovery family tents are manufactured with heavy-duty polyester floors. The floors are coated with a 2000mm PU waterproof coating and factory seam taped. These floors are more durable than PE tarp floors, with a much longer life, and are more resistant to damage from rocks, twigs, roots, and footwear. And unlike PE tarp floor they are quiet to sleep on. Polyester floors cost a bit more, but if you want a better family tent, this is what you want.
Polyester fabric has advantages over nylon when used as a tent rainfly. Polyester is more UV resistant, so exposure to the sun’s rays will not degrade the fabric as quickly as nylon. Also, polyester does not stretch when dealing with water and rain. This allows the entire tent to maintain its proper shape, thereby continuing to protect you from further rain and wind.
The polyester rainfly and floor have a PU coating to keep the water out. For example, with a 1500mm coating, the fabric can withstand a 1500mm column of water for more than one minute before a drop might work its way through this fabric. That is good enough to stop rain in most hurricanes. Discovery Series Adventure Tents have a 2000mm PU coating on the rainfly and floor.
