If it’s not windy and you’re not expecting rain, this is a good emergency poncho / wrap as a just in case. At about $1 and 55 – 70 grams each, it’s not a bad contingency item, in lieu of taking other heavier (albeit warmer and sturdier) rain repellant garmets.
Finally for those that get bored easily, it’s a challenging game piece, to see if you can remove the poncho from the bag and then repack it without busting the bag.
