I’ve had great luck with Kuiu Yukon & Chugach stuff. My First lite omen set has worked great too, the omen is lighter and more breathable than the Yukon set but still very tough.
Another vote for a pelican case. I have one. Make sure you have enough locks for whatever one you decide to use. Not sure about other airlines but with Alaska airlines they state wherever there is holes for a padlock you need one there.
