The Osprey Lumina 45 is the most comfortable and ventilated women’s-specific pack ever made for the lightest loads imaginable. It’s perfect for streamlined weekends or committing thru-hikes. In fact, it’s probably not the right pack for you. It’s for people who pack lighter, go further, and think smarter. This pack isn’t on Instagram, because phones are too heavy, and views look better in your mind anyway. But, if you are one of those maniacal gram-counters, look no further.
