This probably isn't the right subreddit for this, and if I am wrong, please redirect me elsewhere.
I'm getting frustrated trying to research this. We are in the process of planning a week-long trip to California next summer; the plan is to go to Channel Islands, Sequoia, and Kings Canyon National Park.
I know I can fit all our camping gear, such as sleep systems and cookware, into a 120L duffel bag with backpack straps so I can transport them onto the Channel Islands and have our 22-26L daypack with us and for car camping at the other parks.
However, I am also trying to buy a duffel or transporter bag that does it all, allowing me to buy it once, set it, and forget it so that we are prepared for future trips. My girlfriend and I both have 60-65L packs that we would have it fully loaded into a duffel bag to protect our gear from cargo carriers. The only thing that I can find that fits is the Osprey Transporter 150, and I am concerned that it is too big for airport checked bag size requirements.
How does one deal with this, and what do you recommend? I could use our 60–65L as is, having it fully loaded and checked with all straps, hip belt, and compression fully secured and locked but don't want our packs getting damaged via transport.

Thoughts?
I believe the REI Big Haul 90 is what I would need to travel across the country with our camping gear, and is all I would need for car camping, along with our 22-26L daypack for day hikes.
Osprey Airporter Medium - for our 60-65L packs separately for backcountry adventures.
