The Corso Primo ClearTex is a modular travel system built around the KeyFit Max Zip ClearTex extended-use infant car seat. The toddler seat removes so the stroller becomes a lightweight car seat frame, and the seat can face parent or forward with either the car seat or toddler seat. ClearTex fabrics are flame-retardant-free, and the car seat adds headrest height and legroom to stretch rear-facing use. It suits parents who want one stroller from newborn through toddler and a car seat that installs easily; it is heavier and bulkier than a compact umbrella stroller, and the extended-use seat is larger than a standard KeyFit.

Owners rate it highly, praising the easy car seat install, the smooth push and the flexibility of parent-facing and frame modes. Complaints center on weight and folded size.
The Corso Primo ClearTex Modular Travel System pairs a modular stroller with the KeyFit Max Zip ClearTex Extended-Use Infant Car Seat. The stroller can be used parent-facing or forward-facing, with either the infant car seat or the toddler seat. Removing the toddler seat turns it into a lightweight car seat frame stroller.
The removable infant seat insert has moisture-wicking fabric. Used with the toddler seat, it creates an infant carriage for newborns. It later converts to a cushioned seat insert for kids up to 50 lbs. The stroller has a height-adjustable leatherette handle and a compact, self-standing one-hand fold from any configuration. It also has an adjustable FlexCore suspension and treaded tires with foam cores.
The stroller has a large UPF 50+ canopy with a flip-open mesh panel and pull-out visor. The seat reclines in multiple positions and has an adjustable footrest. The child tray swings out of the way. Storage includes the Stash Parent Organizer, which converts to a crossbody bag, and a Zip & Stash basket with dual zippers, organizer pockets and water-resistant fabric. There is also a large mesh pocket on the back of the toddler seat. The basket fob secures items or converts to a travel lock that keeps the folded stroller closed.
