Built on Nature. Backed by Sleep Science.

Drift Baby was created with one goal: to make a sleep sack that truly supports healthy infant and toddler sleep. Decades of research show that babies rest best when their temperature stays stable — and merino wool is one of the only natural fibers proven to do just that.

Unlike synthetics that trap heat or cotton that absorbs moisture, merino regulates temperature, wicks away sweat, and maintains a balanced microclimate around your child’s body. This helps babies fall asleep faster, stay asleep longer, and wake less often from discomfort.

We transformed this powerful natural fiber into a beautifully designed sleep sack with thoughtful details: right-side zipper access, soft flat seams, a safe roomy shape, and our signature embroidered wave.

When you choose Drift Baby, you’re choosing a product that’s gentle, functional, and intentionally designed for the best sleep possible.
