I just finished making a light (2.9 oz) hooded, 1/3 zip, pullover windshirt. I'm really pleased with what I have but I'm thinking that I should give it a DWR treatment, just in case it rains. I would be interested in recommendations of specific DWR treatment products. The windshirt is made of 0.8 oz nylon ripstop. Thanks!
Nikwax TX-Direct, either spray-on or wash-in works well, as does Revivex's product (can't remember what it's called.) The Revivex stuff left some temporary white marks on a Gore-Tex jacket of mine once, but maybe I over-applied it or something.
Most of the lightweight nylons these days seem to have a DWR finish from the factory...does water bead up on it?
Did you use the Momentum 90 from Thru-hiker? If so, give us a full report. I've been thinking of buying some, but at twice the price of the 1.1oz ripstop, I need encouragement.
Bill, I was wrong, I used the 1.1 oz ripstop from Seattle Fabric. For the price difference, I don't mind carrying an extra 0.5 oz. I used a much-modified Green Pepper Oregon Jacket pattern to make the windshirt. Major changes were: No lining, no pockets, no waist cord, lower front panels combined into a single piece, #3 coil zipper w/o a storm flap and other minor changes. I used the Oregon Jacket pattern because of the way the hood is put together in three pieces; much roomier than the two piece hood. I have made the ThruHiker Liberty Ridge windshirt and like my version better; don't know why but it weighs about the same too! If you are interested, let me know and I can send you more detailed instructions. I am really pleased with the results.
I didn't think to check for a DWR finish on the fabric; I'll check sometime today. Thanks!
