Sunny cut is an AI2 nappy to fit babies from approximately 4-19kg. I am sure with some adjustments you can have this fit beyond this range although that is dependent on each child. Nappy features:
4 rise snap options
Single row of waist snaps
1x bamboo trifold, 1 x booster (NB features a dual fold and a full size booster)
Thicker back elastic
Pocket: features upward layered piece with elastic to work on keeping poo out of the casing. Easy to turn inside out if need to be scrubbed too.
Lay in: features a thicker booster to lay over the top of the trifold to help stop bunching.
