One zip from neck to ankle — no snaps to count in the dark.Rockets, astronauts, UFOs — and one very small space explorer about to fall asleep.Forbes named these the best baby pajamas in 2025. The sleeper is the workhorse of the under-layer — soft against the skin, quick to change in the dark, and built to survive the laundry a newborn puts it through.Material. TENCEL™ Lyocell with a touch of spandex for stretch. TENCEL™ is the wood-pulp fiber Lenzing spins in a closed-loop process that recycles 99% of its water and solvents, certified to OEKO-TEX Standard 100.The print. Soft pink ground with multicolored rockets, astronauts, flying saucers, planets, moons, and small stars.Construction. Fold-over cuffs cover the hands for the first few months — no mittens to lose — then fold back when the baby wants them free. A two-way zipper runs chin to ankle and opens from the bottom for diaper changes, the neckline is tagless, and the shoulder and crotch seams are reinforced where a sleeper gets pulled on and off twice a day.Sleepers and sleep bags work together. The sleeper is the layer underneath — it isn't meant to provide the warmth on its own. Pair with a 1.0 TOG TENCEL™ Sleep Bag for a 69–75°F nursery, a 0.5 TOG muslin sleep bag for 75–81°F, or wear alone in a warm room above 75°F if the baby protests the sleep bag.Why TENCEL™ for a sleeper. A sleeper is worn most nights and washed two or three times a week, so we match the fiber to the job: TENCEL™ Lyocell keeps its softness and shape through heavy laundering. Our muslin pieces answer a different brief — swaddles, crib sheets, and 0.5 TOG bags use Tanboocel® Bamboo Viscose for breathability in the heat.Sizing. 0–3M, 3–6M, 6–9M, 9–12M, 12–18M, 18–24M. Size to current measurement. A sleeper that's too long bunches at the hands and ankles and rides up overnight.Care. Machine wash cold and tumble dry low. Don't bleach, and don't iron the printed areas. TENCEL™ keeps its smooth face through the twice-or-thrice-weekly wash a baby's wardrobe demands.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. Common questions Are TENCEL™ pajamas better than generic bamboo pajamas? For longevity, yes. TENCEL™ keeps its surface through repeated, heavy laundering. TENCEL™ Lyocell keeps its face through wash after wash — and no nursery item is washed more than pajamas. The pajamas your baby still has at 18 months are TENCEL™. What temperature should baby's pajamas be? Pajamas are the under-layer, not the sleep system. Match weight to the room: long-sleeve TENCEL™ under a 1.0 TOG bag for 69–75°F nurseries, short-sleeve under 0.5 TOG for 75–81°F, sleeper under 2.5 TOG for 61–68°F. The bag handles the warmth for you. Why fold-over cuffs? No one warns you how fast newborn fingernails grow — or how quickly they end up at the cheeks. Fold-over cuffs cover the hands without mittens that fall off. Somewhere around 4–6 months, the cuffs flip back for good; the hands have jobs now. Browse all TENCEL™ baby pajamas & TENCEL™ sleepers.Free US shipping over $65.
