IDFL test results for new DOWNPROOF fabrics

09 July, 2014 1 comment Leave a comment

Although I've had new 1.1 oz downproof ripstop nylon fabrics up on the site for a couple weeks now, I've been hesitant to announce or make any claims without hard evidence of their performance. Admittedly, I haven't worked with down gear all that much outside of making a few pillows and such (see pic below). I put these fabrics through home tests using 850 FP goose down with good results, but I still felt like I needed more than that to label them "downproof".  

Home Downproof Testing 101: The PILLOW....

Instead of basing the downproof claims off of home testing alone or making generalized statements, I decided to invest the money to have these new fabrics independently lab tested for downproofness at the International Down and Feather Laboratory in Salt Lake City, Utah. I'm very happy to report that our 1.1 oz calendered ripstop fabric received the highest possible rating of 5 on a scale of 1-5. I haven't had time to put this on the site as of yet, but I've also been working on a new, lighter 1.0 oz Nylon Taffeta with a specially designed downproof weave. I'm happy to report that this fabric received the same exceptional rating of 5 on a scale of 1-5

Honestly, even though I've been working through different samples to get these right over the past couple months, I didn't really know what to expect out of this testing. This was my first shot at creating a downproof fabric, but I'm glad it worked out and that it's available to the community. If you're investing the time and money it takes to make DIY down gear, I think you have the right to know exactly what to expect out of your material. Hopefully this helps!

    I just got my order for my 1.1 oz. silnylon and I was a little nervous when I saw it but after reading comments online I’m pretty confident and going to go ahead and try it out for a completely different project than listed. We are diehard beach goers and in the beginning of the season in April & May and the end of the season Sept & Oct. it gets kind of windy and chilly because of it. We use windscreens to combat this. Since it lists it’s good for tarps and other high performance products we’ll see how it works for this. I was looking for something lightweight but durable. Not to mention having a hot pink windscreen will make it easy for my friends to find me on a crowded beach. No one else has anything else like it. Any hints for sewing just straight seams?
