New for 2024! We've taken the original Big Mo 20° Kids Sleeping Bag and added the most commonly requested feature: adjustable open-and-closed cuffs. We've also tweaked the sizing to give it a closer, cozier fit. As always, the Big Mo 20 features thick channels of RDS-certified down, a 2-way zipper, and room to grow for your little adventurers. The Big Mo with synthetic insulation is recommended for average temperatures as low as 40°F/4°C, while the Big Mo 20 can be used in temperatures as low as 20°F/-6°C.
