I have some Zorb inserts and they work really well. My Zorb 2 inserts are thinner though. One Zorb insert (either type) easily lasts through a 3 hour nap and when paired with a hemp insert (or another zorb2 if i had one) it will even make it about 10 hrs or so overnight. They're the only non-natural inserts I'll use. Highly recommend them!
