This backpack is well made, it does pack up pretty small (though I think smaller exist). There are a lot of compartments which is nice, but my complaint is the shape of the backpack. Both me and my boyfriend each got one for a long trip. He is very tall, I am very short and for both of us the backpack is weirdly too long. You have to pack it completely full in order for it to sit right on your back. The top hood is loose and the should straps end up fitting weird. It's also more of a hassle to open and close it, with the two straps and inner draw string, then necessary.
Overall, for the price, I think it's worth it, but I after this trip I will look into better made packable backpacks that are more comfortable.
