This is the Luna 45 + 10; the perfect Backpack for hikers under 6 feet in height. One of the many features of this dynamic backpack is a fully adjustable frame from extra short to extra tall. As with most of these expedition-quality backpacks, there is a lumbar support and very comfortable breathable mesh in contact with your back. Another neat feature is the hidden compartment which contains a rain cover/poncho for both the pack and the wearer. The top, also, detaches which converts into a fanny pack. Size rating is 45 + 10. Capacity is 3700 cubic inches and the empty weight is only 5.15 pounds. Personally, I rate this Luna 45 + 10 a perfect 10 for my wife of 5'2". We ship throughout the US at actual shipping costs only; no handling fee or mark-up. Out of area may pay with PayPal. We offer this pack at the lowest price anuwhere - only $100.00!
