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

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.

The fabric is soft and breathable enough that my little one sleeps through the night without waking up sweaty, which never happened with her old blanket. The zipper runs smoothly from the bottom too, so late-night diaper changes don't wake her fully.

The zipper is so smooth that middle-of-the-night diaper changes don't wake her up anymore, which honestly feels like a superpower. She's been sleeping through until 6am in this thing for three weeks straight now.

The zipper runs both ways, which makes middle-of-the-night diaper changes way less of a wrestling match. My baby sleeps through the night in this thing now, and the fabric is soft and breathable enough that she doesn’t wake up sweaty. Total lifesaver for our whole household.
