Primary school age coat - where zip works!

[Derbybound2022]

I'm never buying school coats from Marks again as my children's zips got stuck daily last year and so they couldn't do it up themselves at school. Can anyone recommend a place where you got your Children's school coat that has a decent zip!

Frugi zips are good. They’re a bit £££ but they come up on Vinted and eBay.

Asda or H&M.
Best coats we've ever had. Seems to vary year to year who does ones we like, but those are the first 2 places I look now.
