i haven't had the chance to try this out in wet weather, so this review is somewhat limited. very lightweight! packs down very small. the fabric has little "fleece" squares adhered to it, and it does seem to lift the jacket off your skin, unlike bare nylon. sizing is true, (i ordered large), layers nicely with a mid layer jacket (ultralight down/fleece etc...), but would be too small to fit comfortably over a large puffy down jacket. 4 stars because i haven't tried it out in the rain, but mostly for the color choices. got the "wheat" color... very bright orange, but if you're trying to be seen that's a good thing.
