Item 2110 is the car-seat travel bag we file before the stroller bag. J.L. Childress still lists a folded size of 6.5 x 5 x 1.5 in, polyester fabric, and $19.99.
The same page names a lockable drawstring, a carry handle, and an attached storage pouch. In-use size is referred to the brand Compatibility Guide, so we do not invent an open measurement.
Shortlist reason: a printed item number and folded dimensions on jlchildress.com.
