Baby Sleep Bag 1.0 TOG in TENCEL™ - Hedgehogs

Standing-in-the-crib season arrives fast. A well-cut bag keeps the legs free to stand and the night warm anyway.

Hedgehogs with acorns and mushrooms — gentle woodland scene.

This is the year-round weight, the one you'll use about nine months of the year in a 69–75°F nursery. It's the everyday workhorse of the line — warm enough for a typical night, light enough that the baby never wakes up overheated.

Material. A TENCEL™ Lyocell shell over a light layer of DuPont™ Sorona insulation, a plant-based fill that holds warmth without bulk.

The print. White ground with watercolor gray hedgehogs holding acorns, small mushrooms, and blue berries, with slender green-leafed trees, butterflies, and ferns.

Construction. Sleeveless on purpose, so your baby sheds heat instead of trapping it. A two-way zipper runs the length of the bag, so a midnight diaper change takes seconds and wakes nobody. The neck and arm openings are bound in soft fabric, not scratchy serged edges, and cut snug — the part that matters most for safe sleep.

Why TENCEL™ for a year-round bag. A 1.0 TOG is worn most nights and washed twice a week, so the fiber has to keep its hand. TENCEL™ Lyocell stays smooth and breathable through heavy laundering and carries heat off the skin instead of trapping it.

Adjacent TOGs in the same print. Room running warm? The 0.5 TOG Muslin Sleep Bag in Hedgehogs covers 75–81°F summer nurseries. Cold nursery in winter? The 2.5 TOG TENCEL™ Sleep Bag picks up at 61–68°F.

Sizing. 0–6M (8–18 lb), 6–18M (18–28 lb), 18–36M (28–38 lb). Size to current weight. The 0–6M usually carries a baby through to the 4-month sleep regression; the 6–18M is usually the size your baby wears the longest.

Care. Machine wash cold and tumble dry low. Don't bleach, and don't iron the printed areas. Wash it Tuesday, wash it Friday, wash it forever — TENCEL™ holds its surface through the routine.

Safety & certification. AAP safe-sleep compliant and tested to CPSC, CPSIA, and ASTM standards. The material is certified to OEKO-TEX Standard 100, and Loulou Lollipop is a Certified B Corporation.
