Lumina 45L Backpack

The Osprey Women's Lumina 45 Backpack is an ultralight, multi-day pack with optimized comfort designed for minimalist-minded, gram-counting trekkers. By carefully packing only the essentials—hopefully all your backpacking products have the word "Ultralight" in the title—the Lumina has a capacity suitable for trips as long as two days. Weighing less that two pounds, it's remarkable how comfortable the Lumina feels with a full load. The ExoForm harness includes seamless, padded mesh at the shoulder straps and waist belt, and the rest of the backpack is suspended off your back with spacer mesh providing complete ventilation. One joy of packing this light is being able to move faster on the trail, and the Lumina is ready for fast-moving pursuits with a Lightwire suspension made of ultralight aluminum to perform with stable support.

I am one with my pack

I've put it through the wringer

I was given the Osprey Lumina 45L from Backcountry, but this review is my personal opinion. I am 5'2", 120lbs, and athletically built, so I went with a small. After a few adjustments to the hip belt and shoulder straps, the pack fit like a glove. (Actually feels like you have nothing on when its empty.) I'm currently using the pack for long day outings climbing and 2 day trips into the mountains. On climbing days, the pack holds a 60m rope, 12 draws, harness, shoes, chalk, jacket, snacks, water bottle, and essentials with room to spare. The brain is substantial for items that need quick access. Side pockets have a cinching mechanism so that stuff doesnt pop out when boulder hopping. I've actually run with the pack on with about 15 to 20 lbs of gear, and it stayed put on my back and was surprisingly comfortable. The mesh on the back ventilated very well, so much to the point, it has a cooling effect. Pretty rad for a sweaty person like myself. So far the Lumina pack has held up against sharp limestone, granite, and tree limbs and still looks new. One downside is the frame comes a little high in the back, so when you look up, you are stopped when your head hits it. I think this can be mitigated with proper adjustment by releasing the top straps out. As someone who wears out gear quickly, the fabric seems to be very substantial even with the lightweight feels to it. Overall the Osprey Lumina 45L fits well, is comfy, and holds up to my daily activities. Update: holds up against sharp stone, thick trees, and dirt. Still looks brand new! It is now my favorite multi-use day bag.
