How waterproof fabrics are constructed

Posted by Elena 19/02/2020 0 Comment(s)

Waterproof fabrics, whether coated or laminated are constructed in 3 different ways. Each method results in different characteristics and possible applications.


2 Layer

A 2 layer waterproof has an outer fabric with a membrane or coating bonded to it. To protect the inner layer a separate lining, often a nylon mesh is needed. The simplicity of the construction means that this method is often used in less technical waterproofs. Because of the compromises in performance and comfort, we don't make 2-layer garments at umkaumka.


2.5 Layer

In a 2.5 layer waterproof the waterproof technology is again bonded to the exterior fabric but, rather than using a lining or third layer to protect the waterproof element, there is instead a coating or paint applied to the surface. This construction is lighter and more packable than 3-layer construction. However, it also tends to be less durable.


3 Layer

In a 3 layer fabric, the waterproof technology sits between the exterior face fabric and a woven or knitted inner fabric. Typically these fabrics are very durable but can be quite heavy. Exceptions to the rule do exist, however, with our Flashpoint Jacket weighing in at just 185g.
