Hello, how are you? I am looking for a stroller for 4 years old boy. We are living in the countryside, and there is a lot of rain here. So I am looking for a strong, wide, and long stroller with a rain cover and footmuff for my kid. Thank you for your advice ahead.
For countryside, harsh terrain, mud and most importantly a lot of space, I would definitely invest in a Baby Jogger City Elite 2 or a Baby Jogger Summit X3. You'll have enough room in there while you'll also be able to go through almost anything. A rain cover and a leg cover/apron will, however, have to be purchased separately (cheaper universal ones are also a possibility). Even pre-owned, believe me, the quality will be worth it.
Another option could be a Britax B-Motion 3 Plus.
