Totally waterproof

I was looking for a light jacket windbreaker and rain barrier. Tested this morning in torrential rain for 1:00, his head under the hood and no water inside the jacket. Sweating side, you will not be at 100% dry (like rain) but excellent ventilation you will not feel "stuck" with the garment. I do not regret this purchase, the price is there, but the product technology too. Fast delivery Thanks Amazon.com
