The sleek and contemporary Blanket 212 evolution from 7am Enfant 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. This both helps the harness stay put and gives you easy access to it anytime you need it. With a water-repellent outer shell, poly insulation, and a super soft micro-fleece lining, the Blanket 212 is warm, weatherproof, and durable. Bonus: it easily converts from a wearable garment to a large blanket, and is machine washable and dryable.
