I did not buy this jacket on Amazon, purchased someplace else. I bought it as a backup rain jkt in the car, got it at a great price. I did the shower test, the outside of the jacket seems to hold onto the moisture, with the jkt getting heavier, but the inside did stay dry for the most part. For some strange reason the lower front of the jacket allowed moisture through, the inside mesh pockets were wet. I may try to use a waterproof spray and see if that helps, but for the price, I would say it's an ok backup, but not for heavy downpours. Invest in a brand name like Columbia as your main jkt.
