What's the difference between the Classic and On The Move Sleeping Bag?

Published in On the Move Sleep Bag
Both styles are made of the same soft 100% cotton knit and have the same TOG rating (0.5 TOG). Additionally, they BOTH feature adjustable shoulder snaps, a double zipper, and a seat belt slot. However, the Classic Sleep Bag is our small bag for babies 0-6 months. It does NOT have the convertible 2-IN-1 walker design feature. The On The Move sleeping bag comes in size Medium (6-18 months) and Large (18-36 months) bag, designed specifically for older babies as they transition into a walker and need the added mobility.
