Pullups Night Nappies advice needed

[StoneBaby]

DS (2.4yo) is potty training during the day but not at night. He is an heavy wetter at night time.

I have tried Huggies Pullups at night but they leak, so last time I put him in Pampers and had the lovely surprise this morning to find that he had removed the said Pampers and pooed in his pjs.

DH is suggesting cable ties to hold the nappies

Any suggestion on which pullups nappies may not leak?

would he not wear ordinary nappies at night?

Huggies do night time pull ups.
There are also under jams .
Both are more absorbent for night time.

I have used huggies night time pullups which have leaked every night they were used.

I never liked huggies nappies and used pampers or tesco own make nappies
