As Featured In
Lightweight, breathable comfort for warm-weather bedtimes — the Loulou Lollipop Short Sleeve Long Pants Pajama Set in Astro Explorers keeps your little one cool and comfortable all night.
Made from TENCEL™ Lyocell with spandex for stretch, this two-piece set actively manages body heat and sweat to reduce temperature-related sleep interruptions, allowing for deeper sleep cycles. Naturally hypoallergenic, moisture-wicking, and temperature-regulating — gentle enough for babies with sensitive skin or eczema.
TENCEL™ Lyocell is made from sustainably sourced wood pulp using a closed-loop process that recycles water and solvents with minimal waste.
Flat seams and printed inner care label prevent irritation. Snug-fit design meets US CPSC flammability standards (16 CFR 1615).
CPSC, CPSIA, and ASTM compliant. OEKO-TEX Standard 100 certified.
Designed in Canada. A perfect bedtime essential.
