What tool bags are y’all commercial techs using?

I’ve been rocking the Klein backpack for far too long. Way too heavy and the convenience of having everything I could possibly need with me at all times is outweighed by the fact it’s about 40lbs. I’m on the tail end of my maternity leave and I have no fucking clue how I managed to carry that thing up ladders while pregnant.

I tried the smaller veto in the second pic for a while, but it was too small for my liking.

I’d love some suggestions.
