Review: Wow! Great product/amazing cust. Service! - Found this product and it was a great price and seemed to be a good built product . It came in 2 days. It was very well built but I ordered the wrong size ,which was my fault. I contacted joywalker via email. Within an hour or 2 the owner Leo emailed me back and asked to measure my pack and they would find the best size to fit my needs. He kept in contact with me and sent a new one at no charge. It came the next day! Fit perfect. There wasn't even any need to return the one I incorrectly ordered! I tested the waterproof of the material Which held water like a bag. Afterwards i still sprayed it with camp dry. The straps are stitched well to the cover and the clips feel very durable. So thank you Leo and joywalker ! 6 stars! Just wish there was more companies with cust. Service like them.

Great cover, much sturdier than the one that came with my OG backpack, easy to put on and nice pouch to put away when not in use, light, the straps are ajustable doesnt have zipper but the buckles are great, fits great on my backpack.
