Writing reviews is not my strong point ,but...
I have used this out in the bush walking under a steady down pour it kept me dry, bar the bottom of my legs ended getting a bit wet ,
I did not sweat underneath that much probably due to it being really cold as it was starting to snow on the tops
compared to the miltec poncho that sell for a extra $20 (I own one ) .I'd recommend the genuine issue hands down over the miltec
as its better built and only 200 grams heavier and
folds down nearly as compact.
using a gotcha strap works really well to scrunch it up tight as .
