Thank you very, very much for the recommendation. Unfortunately, it doesn't look like it's any bigger than the cross-body bag I have presently. In fact, if anything, it looks like it has less cargo space.

I was hoping to have enough room to pack the Steam Deck in its case, accessories, and the Airs in their protective case as well. While the bag you suggest is close to my specs, I like to keep everything in their respective protective cases while inside my carrying medium. I'm so paranoid of damaging my expensive toys that I even bought a thicker after-market case with more room for various cables and small accouterments to put my Steam Deck into. Everything would need to fit in the same carry bag and that one doesn't look to have that kind of space.

Thank you for your time, though. Much appreciated!

By way of comparison, this is the pack that I have at present: BANGE Sling Bag and it just fits the Steam Deck in its own case, plus accessories.
