(durable water repellent) fabric finish repels light rain and snow and decreases dry times. When DWR is used in conjunction with a waterproof/breathable barrier, the DWR finish keeps the outer fabric from becoming saturated so that the breathable barrier can do its job.

Patagonia is actively researching and developing DWR chemistries that will afford high performance and durability with less environmental impact. For more on the challenges and future of DWR technology, please refer to this post on our company blog.
