I've mostly used this backpack for international and domestic travel for the past year, but hoping to use it more for day/weekend hiking trips as well. It's a great size, carry-on compatible, can be perfectly adjusted to your torso (I have an XS, height 5'2"), strong material, lightweight, doesn't feel bulky despite filling it to the brim, and lots of straps to attach items/compress the pack. I can't imagine traveling without it anymore!
