Daylight savings, teething weeks, travel cribs — the sleep bag is the one constant the routine keeps.

Watercolour mermaids — the soft-pastel under-the-sea pattern.

This is the year-round weight, the one you'll use about nine months of the year in a 21–24°C 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. Ivory ground with watercolour mermaids in pastel pink and peach with brown hair, peach binding.

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 Mermaids covers 24–27°C summer nurseries. Cold nursery in winter? The 2.5 TOG TENCEL™ Sleep Bag picks up at 16–20°C.

Sizing. 0–6M (3.6–8.2 kg / 8–18 lb), 6–18M (8.2–12.7 kg / 18–28 lb), 18–36M (12.7–17.2 kg / 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. Two or three washes a week is the baby-laundry baseline — TENCEL™ is built for exactly that cadence.

Safety & certification. Aligned with Canadian Paediatric Society safe-sleep guidance. Tested to Health Canada's Textile Flammability Regulations, and to CPSIA and ASTM standards. Material certified to OEKO-TEX Standard 100. Loulou Lollipop is a Certified B Corporation.

Common questions

Why TENCEL™ for this sleep bag instead of muslin?

TENCEL™ Lyocell is a wood-pulp fiber spun in a closed-loop process. It pulls moisture off the skin quickly and stays soft and keeps its look through repeated washing, so we use it in our year-round 1.0 and 2.5 TOG sleep bags, the ones that get washed most. For the lightest warm-weather layers, you might want our products made with Tanboocel® Bamboo Viscose — like the 0.5 TOG sleep bags, swaddles, and crib sheets.

What TOG rating should my baby wear?

Match the TOG to the room. 0.5 TOG for 24–27°C. 1.0 TOG for 21–24°C, the most common nursery temperature in Canada. 2.5 TOG for 16–20°C cold nurseries. A nursery thermometer removes the guesswork.

What should baby wear under a 1.0 TOG sleep sack?

A short-sleeve bodysuit at the top end of the range (23–24°C), a long-sleeve bodysuit in the middle (21–23°C), or a sleeper at the cool end (21°C). The TOG rating gives you the main warmth; what your baby wears underneath lets you fine-tune from there.
