Winter layering starts with a long-sleeve base that wicks instead of traps. This is that base.Cranes, dump trucks, excavators — and the animal operators running them.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. Light blue ground with construction vehicles (cranes, dump trucks, excavators) operated by elephants, dinosaurs, and cats, with traffic cones, warning signs, and dirt piles.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. Wash it Tuesday, wash it Friday, wash it forever — TENCEL™ holds its surface through the routine.Safety & certification. AAP safe-sleep compliant. Tested to CPSC, CPSIA, and ASTM standards. Material certified to OEKO-TEX Standard 100. 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.
