The one that started it all: Our most-loved, best-selling sleep bag. A wearable blanket that helps baby fall asleep (and stay asleep), so you’re not up all night. Designed to be safe sleep, diaper change friendly, temperature-regulating, and so soft you’ll have to touch it to believe it.

Exterior: 97% Rayon made from Bamboo, 3% Spandex
Highly breathable
J-shaped double zipper
Use as a wearable blanket over pajamas for safer, cozier sleep

Due to lack of quilting, the 0.5 TOG Sleep Bag tends to run bigger and have more stretch. We recommend following our fit guide/rules found in the blog here to determine if it is the correct fit.

Our little one finally sleeps through the night with this thistle-colored bag—it’s like a cozy little cocoon that keeps her warm without any loose blankets. The 0.5 TOG is perfect for our cooler bedroom, and the diaper access makes middle-of-the-night changes so much easier.

The zipper is surprisingly smooth for a middle-of-the-night diaper change—no wrestling required. My little one actually sleeps through the night now that she’s not kicking the blanket off, and the thistle color is prettier in person.

The Thistle pattern is even prettier in person, and the 0.5 TOG is perfect for our warm bedroom—baby finally sleeps through the night without overheating. I love that it's a wearable blanket, so no worrying about loose covers in the crib. Diaper changes are quick too, since the bottom just unzips.
