????Top Lid:An extension collar with two drawstrings on the top allows you to expand the pack and increase the main compartment capacity by 5 liters.
????Hip Pockets:There are also a pair of small hip pockets on the belt for storing snacks, sunglasses, etc.
????Walking on a Rainy Day:There is a waterproof cover in its own zippered compartment at the top of the pack. It covers the entire backpack.
