    Comments about Britax Marathon 70-G3 Onyx:

    Being a rather taller and larger individual I need to have alot of leg room while driving. This carseat is smaller yet still of high quality. It is also nice to have until our son is ready for a booster seat.

        Comments about Britax Marathon 70-G3 Onyx:

        We have only had this seat a few days but so far I love the easy latch system and it seems comfortable as my son fell asleep on his very first trip. Also love that the seat cover is so easy to remove. It is a bit on the heavier side but not horribly so.

              This one seems even better than the Marathon 70 we purchased a few years ago for my other child. Love the additional padding on the straps.
