Carry-on sized pack for travel, hiking, and fitness

Hello everyone here. I am looking for one bag that can meet all my needs while travelling and at home.

I want to find something that will meet the 45" overhead rule for flying, staying active away from home, and also be useful in between trips. I like to do a lot hiking and backpacking and also would like to use a bag to add extra resistance for bodyweight exercises. I'm thinking being able to carry up to 40-50 lbs in the bag comfortably would be enough.

I have used a GoLite backpacking bag in the past but would like to find something less distinct. Been looking at the Hill People Gear packs, but honestly don't know what all is available.

​

TLDR; I want a bag that can comfortably transport 40-50 pounds during strenuous activities while looking nice and fitting in an overhead airline compartment.
