Spray DWR on Clothing?

Question:

If I spray a DWR finish on clothing, will that also increase its wind resistance? Specifically I’m thinking of a pair of light gloves and a headband that I use to meet an early morning chill, but are not much help in a cold wind. I find most windproof items too bulky.

Answer:

DWR sprays are only designed to work on tightly woven shell fabrics (in other words, don’t spray your fleece with it!). Theoretically, a DWR spray should very slightly increase the wind resistance of shell fabrics, but the difference will be negligible and probably impossible to perceive. May I instead suggest a few items to put on your Christmas list? Here’s a very un-bulky windproof headband that’s cozy and affordable ($18):

And these gloves fit the same bill (light, streamlined, warm and windproof):
