I have a flat bar but changed to a flat swept-back pair which is a little better.
I found the Brompton flats too narrow and it started to play with my shoulders.
These bars plus the ergon bar grips/ends are great; I use the bar ends loads. These bars also have a small amount of sweep too.
Yes, from the product description:
