Safety Cat Travel Carrier Recommendations?

When we had our Henry we had a soft sided carrier that had a rigid frame that collapsed. I've forgotten the brand, but it folded flat and ended up about 2-3 inches wide with the footprint of the bottom of the carrier. They have a huge selection on Amazon or Chewy.

BTW, Henry quickly adapted to travel and preferred to sleep on the bed in back during travel. It was a safe location and he didn't try to wander so we just brought the carrier along just in case.
