I have several sized packs, and this is my new go to pack. I bought it for a day pack to hike with my wife and daughter, and hauling most of our gear. Ample room for lunch, snacks, packable jackets, water, etc. Loaded at around 30-40 pounds is still comfortable, and breathable. I also use this pack as a Get Home bag, which has everything I need to survive an emergency for at least 2 days. MREs, water, fire starter, shelter, bivy sack, and warm under layers, fits everything, and yes, still comfortable, buy this pack, you'll love it!
