After receiving the backpack, I can't wait to carry it out. There is an adjustable Helmet Pouch on the front of the backpack, which can be used for helmets or clothes. This adjustment function is great and it can better fix my helmet. The product page says that the backpack fabric is water repellent. I tested it and poured water on the backpack. The water did not penetrate into the backpack. The water repellent function is ok! In addition, the quality of the backpack is very good, beyond its price point, and the details are well done. I like this backpack very much, it fits all our bike trips/backpacking/camping adventures in PNW. It is much more than I thought, and it can easily save everything a person needs for the weekend. The bright blue is also very useful, just in case you get lost!
