OK. This was an experiement. I needed a light waterproof outer cover for my large sil-nyl stuff sack that I strap on my external frame pack. Because of the cost of the sil-nylon stuff bag, I simply wanted to prolong its life. It did not have to be exceedingly strong, because the inner bag basically takes all the stress. So I bought a $4 kids poncho (Coleman) at WalMart. I cut out a bag and sewed it up. By the time I finished sewing there already were tiny holes simply from handling the material. So, if you really want a poncho for your kid, DO NOT use the Coleman el-cheapo! It would probably last 5 minutes on a kid!
I need an outer bag to protect my expensive sil-nylon bag from rips when I go off-trail. I do not want to trash a $25 bag everytime I go out. I have been using an old REI packcloth stuffsack and it is now full of tears and holes. I was looking for cheap material to make a cheap light outer bag. A plastic bag would just get ripped up. Anyway, the post was essentially about how flimsy and worthless the material is on Coleman ponchos.
OK. I guess a lot of folks have never used an external frame pack. When using an internal frame, you put your sleeping bag in a light (say sil-nyl) bag and then put that bag in the bottom of your pack. Your pack acts as the outer bag. With an external frame pack, you use a stuff sack and tie this on the bottom, under the packbag. Bulky stuff goes in here - be it sleeping bag (stuffed in its own bag), tent, pots and pans, etc. The external bag takes a beating, so will not stay waterproof long. Similarly, an internal frame pack takes a beating and will not remain waterproof - hence - they are usually not made of waterproof material. Since the bag I want for my external frame pack will get ripped and poked, I am looking for something tough but light and mainly cheap -ideally cheap enough to be disposable - simply throw it out after each backpack season. Tyvak comes to mind, but it is hard to buy small quantities. The large size oxford cloth bags sold at REI weigh about 4 ounces. But it is not cheap - yes cheaper than sil-nyoln. I am just trying to think of a better solution.
send me your info and the size of tyvek you are looking for...i think i have roughly 3 feet of the std width roll left from my groundsheet...i obtained for free so i will certainly share the wealth...and its pretty tough i imagine you'd get a few trips out of it...at least it would take nothing more than your sewing time to test
I do it because I can...it also helps that you are not there...

Hey Daisy, what about cuben stuff packs? I went looking for cuben to make a tarp out of, but when I went searching all that came up were cuben stuff bags. Not sure of the price though, I am sure more than 4 bucks

Thanks for the ideas. Cuben is expensive. I have an Ursack - do not want to stuff my sleeping bag in something that has food odors. Thanks for the tyvek offer - but I ran out of time - am leaving on my BIG trip Tuesday at the crack of dawn! So I bought a granite gear nylon sack- $12 and 3.2 oz. A bit over what I consider "Cheap" and certainly not as tough as I would like.
