25L Waterproof Backpack - Hiking Backpack, Packable Backpack for Travel, Small Foldable Bag - Nylon Ultra Lightweight Daypack, Day Backpack for Men and Women Drop-Proof Inflatable Insert

The AirBags 25L Ultra Lightweight Packable Backpack is a great option for those who need a compact, lightweight, and spacious packing cube. It has two completely separate sections, which makes packing great. The top compartment is large enough to hold a 13" laptop, and there is still room for a 15" laptop. The adjustable cord is intended to secure the neck of a water bottle placed in the side pocket so that it doesn't fall out. The backpack is perfect for a few items and kept everything dry while visiting Niagara Falls. It does a great job of repelling rain and spray, but it is not recommended for submerging. The inflatable pad does not hold the air, and the inflatable insert needs to be purchased separately. Some users found the inflatable inserts not especially useful, as they aren't reliable, become flat, and don't last long. The backpack is ultra-light, so the straps are lightweight but may not be suitable to be used as a backpack for an extended period. The company offers excellent customer service, as one user reported that they had received a replacement the next day.
