What's inside.

• 1x TENCEL™ Sleeper in Mermaids — the everyday under-layer, Forbes "Best Baby Pajamas" 2025.
• 1x 1.0 TOG TENCEL™ Sleep Bag in Mermaids — the year-round sleep bag for 69–75°F nurseries, part of Loulou Lollipop's Good Housekeeping 2025 award-winning sleep sack line.

The print. Ivory ground with watercolor mermaids in pastel pink and peach with brown hair, peach binding.

How the two pieces work together. The sleeper handles the under-layer warmth at 69–73°F nursery overnight. The sleep bag carries the 1.0 TOG number. Together they're the working sleep set for the most common US nursery temperature overnight. Add a 0.5 TOG muslin bag for warm summer rooms or a 2.5 TOG for cold winter rooms and you've covered the full temperature range — but most households start with this set and add on later.

Materials. TENCEL™ Lyocell throughout. Wood-pulp fiber from Lenzing produced in a closed-loop process — 99% of water and solvents recycled. OEKO-TEX Standard 100 certified. The 1.0 TOG bag includes DuPont™ Sorona insulation, a plant-based polymer from corn-derived feedstock that holds warmth without adding bulk. Both fibers hold their hand through fifty wash cycles, which is why the bundle ends up still in rotation at 18 months instead of in the donation pile.

Why bundle instead of buying separately. Two reasons. The bundle saves 15% on the set versus the individual pieces. And the pieces are designed to work together — the sleeper as the under-layer, the bag for the TOG warmth — so you don't end up with mismatched weights or mismatched prints across the nursery.

Adjacent products. The 0.5 TOG Muslin Sleep Bag in Mermaids extends the set to warm summer nurseries above 75°F. The 2.5 TOG TENCEL™ Sleep Bag handles cold winter rooms below 68°F. For walking toddlers past the closed-leg sleep bag, the matching 1.0 TOG sleepsuit is the next step.

Sizing. Sleeper 0–3M, 3–6M, 6–9M. Sleep bag 0–6M (8–18 lb), 6–18M (18–28 lb). Size to current weight.

Care. Machine wash cold, tumble dry low. Both pieces hold up through repeated washing. Do not bleach. Do not iron printed panels.

Compliance. OEKO-TEX Standard 100 on the fabric, CPSC/CPSIA/ASTM on the garment, AAP safe-sleep guidance on the design. Loulou Lollipop is a Certified B Corporation — a third-party audit of how we treat people and the planet, not a self-claim.
