DWR is an acronym for Durable Water Repellant
dur-abl wa-tr ru-pel-ant
DWR is a style of finishing technique used to help the fabric not absorb water. Nearly all of our fabrics are finished with a DWR coating because this often affects the durability over the lifetime of a fabric. The two most common types of DWR are C0 and C6. Traditionally, DWR uses perfluorinated compounds (PFC) which can be detrimental to the environment. Ripstop by the Roll is in the process of transitioning all of our new and past products to use a PFC Free DWR.
