The Ultimate Adventure Suit for Tiny Trailblazers

The Big Mo isn't just a sleeping bag—it’s a wearable hug built for s’mores, flashlight tag, and early morning tent snuggles. Designed for the "I can do it!" stage of life, this bag gives your toddler the freedom to use their hands and get in and out on their own while ensuring they stay toasty-warm once the stars come out.

Which Big Mo is right for you?

Toggle between our two insulation levels to find the perfect match for your next trip:

20° Down (The Backpacker’s Dream): Insulated with 650-fill power RDS-certified down. This is our warmest and most compact option, weighing only 11.6 oz. It compresses down to the size of a large water bottle, making it the gold standard for family backpacking or high-altitude camping.

40° Synthetic (The Versatile All-Rounder): Filled with cushy, hi-loft polyester fill. This is the "worry-free" bag—it stays warm even if it gets damp and is incredibly easy to wash after a weekend of s'mores. It's the ideal choice for summer car camping and humid environments.

Standard Features

Signature Adjustable Cuffs: Now standard on both the 20° and 40° models! These fold-over cuffs allow toddlers to use their hands to read books or hold a flashlight, then flip closed to seal in heat once they drift off.

Kick-Proof Design: Unlike traditional rectangular bags that toddlers slide out of, the Big Mo is worn like a cozy suit. It stays perfectly positioned all night, ensuring no 3:00 AM wake-ups because the blankets fell off.

Two-Way "Easy-Vent" Zipper: Zips from both the top and bottom. Need to cool down warm toes or check a pull-up? Just unzip the bottom while keeping their core cozy.

Built to Last: Made with a durable PFAS-free 100% Ripstop Nylon shell that resists snags and spills while remaining soft against the skin. Backed by our lifetime warranty.
