Waterproof tent material can be made from a number of different materials including canvas, nylon, and polyester. Some people believe that nylon or polyester are the best options because they do not absorb any moisture as canvas does. These materials are also lighter than canvas, so they can be used to make lightweight tents.However, there are some issues with waterproof tent material (nylon or polyester) that need to be noted.The first problem is that the plastic coating used on the fabric can rub off when you’re camping. If this plastic rubbing happens regularly, then it will degrade and lose its protection against water. The second problem is that this material cannot be completely waterproofed or it will affect the fabric’s elasticity and strength.A number of tents are made from canvas rather than nylon. This material is not as waterproof, but it does breathe better. Canvas is also much more durable and can be easily repaired when worn.
