It is water resistent, but not waterproof. Its is definitely wind resistent. I have gloves & a hat made of it. It works well in LIGHT rain/mist, but certainly isnt waterproof. The seams arent taped, water runs in that way. Also, it isnt breathable, simply because the membrane is essentially sandwiched between two insulating layers, and the temp difference isnt enough to allow perspiration through. IMHO, I LOVE windstopper gear for what it is; insulted clothing, without the bulk of 2 layers. But, if youre expecting moisture, best to go with a shell outer & pile jacket.
