Full Belts discussion

Hello everyone, I am considering switching from my steel cages and cb3000 models to a complete belt similar to the one pictured below. I was curious if anyone here owns a full belt. My main question is, how do you handle sitting since the front panel stays stiff…is it an issue? Any insights or personal experiences would be much appreciated. Cheers Starflyer s-l225.jpg

Does anyone here actually have a full belt?
