MAGCOMSEN Men's Hooded Windproof Water Resistant Rain Jacket Windbreaker 5 Pockets for Hiking,Fishing,Travel

Is the jacket 100% waterproof? No water getting in?

I am 165 5'9" should i order a medium or a large ?

My wife purchased the xxl for me. im 5'8" and 220lbs. it seem long and a little too roomy on me. would the xl be a better fit?

My husband is 5'8" and 215 lbs. will the xl fit or should i get him the xxl?
