This shot of Jeff Liskay (Patagonia fly fishing ambassador) struck me as a very clear illustration of the function of a garment’s DWR. Click on the picture to see what I mean. What is a DWR? A DWR is a “finish” that keeps the outer fabric from becoming saturated so that the breathable “barrier” can do its job. DWR finishes are the first line of defense in preventing water entry. Patagonia waders, jackets, vests and packs all have DWR finishes. In most cases it’s a proprietary technology called Deluge DWR, which lasts longer than standard DWRs. Garments with the Deluge DWR finish can have good repellency even after years of use. Eventually DWRs wear thin and aftermarket applications are the remedy. Oh and by the way, the picture also struck me as a nice shot of Jeff and his catch. Stay dry everyone. Let me know if you want to have a DWR (durable water repellent) conversation.
