The sleek and contemporary Blanket 212 evolution keeps little ones toasty from head to toe on mountain hikes, chilly city streets, and everywhere in between. The smart design allows you to size it up or down using zippered length and width extensions so it can actually grow with your child from 6 months to 4 years old Other notable features include simple hook and loop attachments that fit any stroller, plus a removable anti-slip back panel that eliminates extra fabric between baby's back and the harness for car seat use.
