Good safe bet would be some Easton bars with their 9 degree back sweep. I’d look at the low rise EA70 (aluminium) or EC70 (carbon) or one of the Race Face bars.
But you could try something with more sweep – eg surly bars etc. Maybe it is not the width of yours but the back/up sweep or rise? I’d go to a shop and try as many in your hand as you can.
You can always cut down your bars if it is the width.
I would strongly avoid bike manufacturer branded bars that come with bikes unless they are component brand name ones (eg Easton, Race Face etc) as they are can sometimes be a bit cheap and heavy as they expect you to fit the bars of your choice after.
you could also look at CRC and order a few different ones and see how they feel and send the ones you don’t want back (free returns).
2nd hand most sub 700mm bars go for peanuts now so take your pick if you want to go that route and save some money.
