I was using disposables at night with dd as she'd outgrown her nappies but was still seldom dry at night but I hated them. After a few months I realised that night time dryness was a long way off so I've bought a couple of Minki yo-yos. I got XL which are for age 3-7! They're enormous on but she loves them. One is zebra patterned so she calls it her "giant zebra bum"! They're pockets but don't come with any inserts which makes them a bit cheaper and you can stuff them to fit your needs. As I'm washing nappies regularly for the little one anyway I've only got 2, the nappies dry quick and I use whatever inserts are handy so this has been enough. They have poppers at the side so can go on and off like a regular nappy but they're stretchy enough to pull up and down like pants too.
Don't know if they would suit you but I've found them useful although the L may have been big enough
