Recommendations for warm sleepsuits?

[Skyla01]

My LO sleeps is a sleeping bag and I follow the guidance for layers of clothes & room temp, and aware important not to overheat baby. However I think some of her early morning wakes are due to her being a bit chilly. I have two slightly thicker / fleecy suits and she doesn't wake as often with them on.

Any recommendations for similar? The suits I have are hand me downs so I can't buy more. Baby shops near me have all shut down so can't go and browse.

My dd was a terror for getting any covers off, her cot was in a cold spot (no choice) and it woke her up. I bought onesies which were really thick (like a duvet material) I think boots or John Lewis. I also sometimes used 2 or 3 thinner ones with the first one on being in that fitted and next one up being larger size.
For her she hates any physical restrictions so onesies worked better cos she could move any way she liked. We all slept better after that.

I used to get them in Primark. Unfortunately, in winter.

Last time I was at the supermarket, I saw babygros with a tog rating (2 I think). So the onesie itself was made out of sleep sack type material.
This was at Morrisons but it might be an idea to search online?

Thanks for the suggestions. @Cupcakegirl13 I've ordered a few from next. Never tried ones with zips before!
