Very good size for a day pack. Made of excellent durable material. The pack is a little as you may expect from waxed cotton and leather . As long as you don't mind the extre weight go for it.
If there were 6 stars or more, that is the rating I would give this backpack. As said by others, it has traveled with me all over the world for at least 10 years (I've lost count). Still tough and intact. I still receive compliments on it, even today.
