Sleep Bag in Basil 0.5

$25 ~~$50~~ In stock

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.

The zipper glides so smoothly that middle-of-the-night diaper changes don't wake her up at all, and the 0.5 TOG weight is perfect for our warm bedroom. She's been sleeping two-hour stretches longer since we switched, which honestly feels like a miracle.

My little one actually stays asleep through the night now, and the 0.5 tog weight is perfect for our warm bedroom. The wearable blanket design means no more kicking off covers, which has made middle-of-the-night wakeups almost nonexistent.

The zipper is so smooth that middle-of-the-night diaper changes don't wake her up anymore, and the 0.5 TOG weight is perfect for our warm bedroom. She actually sleeps through till morning now, which I didn't think was possible.
