These are the 3 largest packs that I carry for hiking and hunting.

On the left is the USMC Main Pack (81 liters), in the middle is the South African Defense Forces M83 rucksack (77 liters), and on the right, the Swedish LK70 rucksack (70 liters).

I didn't go into too many specifications because there are many other videos regarding each one, but I can answer any questions that you have.

The main purpose of this was to put together these 3 packs next to each other for a little comparison.
