Narrow double pushchairs

[Mindisboggled]

I'm just about to order the mountain buggy duet but before I do was wondering if there is any other double side by sides that are narrow.
The out n about nipper double is too wide. I cant seem to find via google if there is anything between mountain buggy and the nipper so calling other parents for their input

I've got a babyjogger side by side and it fits most places. The only place it does not fit is the basket only aisle in Waitrose

Just had quick Google of the baby jogger it's the same width as the nipper. I really like the look of it though. It's much more stylish than the duet.

There is a cosatto side by side that’s narrow.

Can’t remember the exact one but it was 2 strollers together not like the mountain buggy
