Can you recommend a rugged but lightweight stroller?

[LaTristesse]

I need a stroller for the MiL to use - it needs to be lightweight and fold down easily (to fit in a smaaaall car), but should also be rugged enough for long walks in country parks. DS is a year, and we'd like it to be comfy enough for him to sleep in, and be used for a couple of years at least...

Can anyone recommend one which might fit the bill? Thanks...

Baby Jogger City Mini.

Out and about nipper 360 really good should fit the bill. Very rugged and lightweight - just might not be quite small enough folded but its not too bad v easily goes in my golf's car boot.

Thanks ladies.

I should also mention the MiL is under 5ft, so one with low or adjustable handles would be cool!
