I've tried both DriDucks and O2 Rainshield. In my opinion, the O2 gear is much better built, more comfortable, more breathable, and quite a bit more durable. My set in large cost about $20 a piece for pants and jacket on Amazon, and weighs 4.15 oz. pants, 6.0 oz. jacket. The O2 seems to tolerate pack straps well, and packs quite compactly. The jacket is breathable enough that it could also act as a wind shirt if needed.
