While I haven't had the chance to test these in Monsoon-like conditions, they did take on some nasty storms in South America. They managed to stand up to the test and keep all my belongings dry. They are also breathable enough so moisture does not build up inside of them. The elastic fit strap makes sure they fit to a very wide range of bags, as I used them on both Arkel and Nashbar bags. They are also very light and pack down very nicely.
