I commute in my motorcycle everyday (summer, fall, winter and spring) to work in Seattle (about 25-30 miles each way) so a waterproof bag is critical. this bag is not. the zipper for the laptop compartment gets really wet and drips in the inside.
The outside of the bag is made with some canvas that gets wet and takes for ever to dry, so I ended up to spry it with Nikwax TX.Direct Spray-On Fabric Care which made things better but does not last since it rubs off against my clothes.
I wish I could send it back because this bag is not worth the money if you are a bicycle/motorcycle commuter.
Too bad! I was really wanting this bag to work
