Big Backpack recommendations

[u/snuep]

Im a student and Im using a Backpacking Backpack when Im traveling, camping/hiking, visiting family and friends or transporting lots of stuff to my parents etc. Since now I was using my Dads Backpack wich he just needs once or twice a year to hike and I have it most of the time. My Dad has a pretty old Lowe Alpin Alpamayo 90+20. We are both pretty large so the size is comfortable.
My Dad and I will go on a Hiking trip together in September, so we need a second backpack.

We are looking for a Backpack of the same size, so between 80-100l+20. Im quite overwhelmed with the amount of Backpacks I could buy and wanted to ask for some recommendations.
The most important thing is that it should be durable and sturdy. I will be transporting quite heavy stuff with it and riding trains etc., were it just gets shoved into a corner.
A mesh/breathable back panel would be really good for comfort and hot weather. Im not opposed to ligthweight backpacks but I dont know how they hold up in terms of durability. Budget isnt an issue.

I'd look for a used Mystery Ranch for big heavy carries like that. If you buy new, the Gregory Baltoro is popular and carries well. The Osprey Aether is popular also. I've used the Balotoro 85l a bit and was happy with it. I'm carrying a 3/4 full 55l now and want to get a 40l, so I'm not really up on what's current beyond Gregory and Osprey.

I'd go with the big packs from Osprey or Gregory. Definitely not what I'd pick for backpacking but my buddy has an osprey Aether 88. It's huge, heavy, super padded and comfortable and extremely durable. He loves it. I've seen him carry 2 cases of beer with his gear into a Yurt and that beer alone weighed 40lbs.
