Baby Jogger Summit X3 vs Chicco Activ3
A $160 gap in price, and the stroller that costs more is the heavier by only 0.9 lb, 28.44 lb for the Summit X3 against 27.5 for the Activ3. The real differences are the child limit and the car seat. The Summit carries 75 lb and the Activ3 50 lb. The Activ3 takes any Chicco infant seat through an included arm bar, which makes it a trail-capable newborn setup for a KeyFit owner; the Summit needs adapters, sold separately, for City GO and Graco SnugRide seats. Chicco's hand brake is a parking brake, not a running brake. Owners say the Activ3 handles gravel and brick sidewalks, but call the organizer flimsy and the seat unable to face the parent. The Activ3 folds with one hand and stands, to 23.3 x 25 x 37.5 inches; Baby Jogger publishes no folded size for the Summit. Chicco's parking-only hand brake is the dealbreaker for anyone who plans to run, which leaves the Activ3 to Chicco-seat families who walk.
Only Chicco publishes a folded size for its model here; Baby Jogger gives none for the Baby Jogger Summit X3, so only one side gets a carry-on verdict. The Chicco Activ3 is 0.94 lb lighter by its maker's figure (27.5 lb to 28.44 lb). The Baby Jogger Summit X3 is newborn-ready as sold; the Chicco Activ3 needs a bassinet, insert or infant car seat for the first months. Chicco KeyFit / Fit2 seats click straight onto the Chicco Activ3; every seat listed for the Baby Jogger Summit X3 needs an adapter.
