OBO! If you're chasing a sub 10lb base weight, this pack might be right for you! It weighs 1.8lbs yet has a frame, supportive hip belt, and ventilated back. I love the way this pack fits to my body, I'd best describe it as 'soft yet supportive'. Where other packs create pressure points, this might not. Unfortunately my torso size demands a sz small - thus, selling this because it is a Medium frame size. Torso length is not adjustable, but the Small-Medium-Large range is standardized so you can measure yourself and see if a pack fits. FWIW, it's in great shape and doesn't have any kind of smell to it. That's always nice.
