1.4oz No-Sew DCF Emergency Rain Jacket

It is great to experiment.

I made a poncho tarp that worked great as a poncho on the 100 Mile Wilderness.  It had good air flow. It weighs 4.6 Oz. I did seams similar to what you did. I reinforced tie points.
This does not include weight of stakes. I never tested it on the trail as a tarp.  It worked good in the yard.  I hope to get back on trail someday and test it out as a tarp.

Very cool and absurdly light.  Would be a nice piece on trips in dry climates with no rain in forcast.  Just remember, Chief Sohcahtoa can only calculate right angle triangles ;)

Cool. Nicely done. I could definitely see using it when the weather is supposed to be good.

For day hikes, I tend to leave the rain jacket at home if the forecast is good (0% chance of rain). Unfortunately, I sometimes space out and don’t put the rain gear in there when its not (10% chance, and things turn sour). This would be way more comfortable than getting soaked, even if it is clammy. It is so light you can stick it in your pack (with things like a space blanket) and keep it there all the time.

Likewise, I never go backpacking without rain gear (even when the weather is supposed to be great) and this could save a few ounces. Nicely done.

Thanks everyone.. exactly my thinking on the usage. Guess we’ll get some rain in California eventually so I can try it out and see how comfortable it is.

Sure, but any triangle can become a right triangle with the addition of one well-placed line :)

How about making it out of heavier Cuban? Probably still only 3-4 oz and much more durable.

Yeah, timmermade makes one out of 0.5oz DCF. I think anything under 1.3oz weight DCF wouldn’t be much more durable, and above 1.3oz you’re looking at 3-4 ounces for the jacket and you might as well get a woven WPB/DWR jacket since there are some in that range. So that’s why I consider it an emergency jacket – definitely not durable enough for daily use.

I love this project!!!!  Great job.  And thank you for sharing it!

You guys should take a shot at a DCF version of the Hennessy rain cape/tarp

Nice job on the build. While not likely ideal for rain, it looks perfect for a vapor barrier top for winter camping. Make a pair of pants and socks and you could improve the comfort range of your winter set up by at least 10 degrees and likely more.

That is insane how light your creation is.  Taking a closer look, it would definitely fit a need on certain trips.
