Vista V3 Stroller + Aria V1 Infant Car Seat Travel System

3 major issues. For winter/fall babies only. Vinyl warning label on lower back of seat causing sweat and over heating, summer babies beware. Crotch seat buckle not adjustable like Mesa or other brands, a chunky 6-7 month old thighs get pinched, therefore already outgrown. Lower back has hard rectangular ridge once newborn insert removed, uncomfortable to the touch, no cushion behind seat cover. I liked this seat in the winter and for a newborn until the flaws presented themselves. Lightweight design doesn't really matter as I thought it would, baby gets too heavy to carry regardless, except from car to inside house. Have used with ridge and minu v3 with adapters, no issues.
