I've use it in the rain and I haven't gotten wet yet. I got the 3xL and the stuffing pocket isn't big enough, I can barely stuff the jacket and zip the pocket. Also I wish it had D rings in the inside of both pockets so that I can attach a knife sheath or a fire starter on a lanyard. That said I really like the jacket. You won't regret buying one. I take it everywhere, mine smells like fish. Going to buy another one for work and be part of my EDC kit
