How big is men's outdoor camping equipment backpack, 60 to 75L?

Large bags over 60L are mainly used for many days and long periods (more than three days), and small teams are too conceited.

If you just walk for a day or two, or travel in a big group, a lot of equipment can be shared (such as tents, pots and pans, fuel), so there is no need to find abuse yourself. Carrying a big bag is glamorous, but it is also really tiring. Sharing some complementary equipment with teammates will reduce the load. At this time, a 45L bag is enough.

If you really need a big bag over 60L, I suggest not to take 70L, which is really too big. Many 60 or 65L bags can be upgraded, and the bundle under the head bag is slightly loose, which can extend many volumes and can hold more than 70 liters. It is also convenient to shrink the size of the backpack when there are few things in the later period.
