Long-Sleeve Pajama Set in TENCEL™ - Stargazing Bears

Soft enough to fall asleep in mid-story, warm enough to stay asleep after.

Polar bears and their cubs under the northern lights — Arctic bedtime.

A two-piece set for 65–72°F nights — the rooms where a full sleeper runs warm but a short-sleeve set runs cold. Long sleeves on top, long pants below, in a fiber that moves heat off the skin instead of trapping it.

Why a two-piece set. A full sleeper runs warm in a mild room and a bare bodysuit runs cold. The two-piece set sits between them, covering the legs without overheating the core.

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. It's softer than cotton and keeps its shape through heavy washing — the pajamas your baby still has at 18 months are TENCEL™.

The print. Deep navy ground with white polar bears and their cubs gazing up at the northern lights — aurora swirls in teal and blue, with stars, moons, and constellations.

Construction. A two-piece set: a tagless top and a pull-on pant with a soft, non-binding waist. No zippers and no snaps — the set for the stage when the baby helps get dressed.

TENCEL™ vs cotton pajamas for toddlers. Cotton pajamas are the default and the reason most toddlers end up with a pajama drawer that pills, fades, and shrinks within six months. TENCEL™ Lyocell is a longer fiber than cotton and holds its surface through more wash cycles. For a garment that goes through the wash three nights a week, the difference compounds. The two-piece TENCEL™ set is the pajama the toddler still wears at age 3.

Adjacent products. The natural next step from a sleep bag for toddlers who refuse the closed-leg sleep bag once they're walking. Browse the full pajama and sleeper collection or pair with a 1.0 TOG TENCEL™ sleepsuit for the in-between phase.

Sizing. 12–18M, 18–24M, 2T, 3T, 4T. These run true to size. A toddler at 24 months who's also 50th percentile for height usually fits the 2T comfortably.

Care. Machine wash cold and tumble dry low. Don't bleach, and don't iron the printed areas. A baby's laundry schedule is relentless; TENCEL™'s surface doesn't notice.

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.
