This is a very lightweight backpack that will tuck it's self into a pocket for storage when you don't need it. When opened it holds alot of stuff is hard to snag and repels water. There are side mesh pockets for water bottles and the zippers have pull strings to help find and use them. The back straps adjust too. #rankboosterreview #Sponsored #Huwaijianfeng https://www.amazon.com/Lightweight-Foldable-Backpack-Resistant-Waterproof/dp/B073XLSJ9P
