This was the first pack I ever purchased -cheap, not ultralight (3.3 lbs I think) but the thing is actually built really well - I've had it for 3 years and taken it on many overnight trips and it's still in great condition even in rainy and muddy conditions. At the very least its been good for packing up and using as luggage on airplane trips. The straps are better than some of the pricier packs I've tried on - by all means not the best but a decent gateway to backpacking
