Donald A.wrote a review of Osprey Packs Hornet 24 Backpack - 1320-1440cu in on February 1, 2016
Familiarity: I've put it through the wringer
Close to ultralight. I hate how so many packs feel heavy even before putting anything in the pack. Not the Osprey Hornet.
The size works well for all my day hikes. It fits 2 to 3 liter reservoir, lunch, jacket, and emergency supplies.
My only complaint is the breast strap is too close to my neck. I bought the small size Hornet 24; perhaps the large size would fit me better.
