The sleek and contemporary design keeps little ones extra cozy 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 grow with your child from 6 months to 4 years old. More 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 helps the harness stay put and gives you easy access anytime you need it. With a water-repellent outer shell, poly insulation and a super soft plush 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. This smart design keeps little ones toasty from head to toe.
