Loulou Lollipop Tencel Sleep Bag 2.5T - Sushi

Deep-winter nights meet their match: the TENCEL™ Sleep Bag, rated 2.5 TOG, pairs a waffle-knit TENCEL™ Lyocell shell with a fuller layer of DuPont™ Sorona® insulation, built specifically for the rooms that never quite warm up. Rated for a cold 16–20°C nursery, this is the winter weight of our sleep bag line.

The textured weave traps air more effectively than a flat knit, which is what allows this bag to stay genuinely warm in a cold room while remaining just as easy to move in as the lighter-weight bags in the line.

Clever Stay Put Design

Baby can't kick it off, meaning fewer wakeups (for them and for you!)

Quick And Easy Diaper Changes

Unzips from the bottom so you never have to fully undress your baby — even at 3am.

Built for Cold Rooms

A fuller layer of DuPont™ Sorona® insulation under a waffle-knit shell for warmth without trapping heat — safer for sleeping in a 16–20°C nursery.

Construction: Sleeveless on purpose, so your baby sheds heat instead of trapping it. A two-way zipper runs the length of the bag, so a midnight diaper change takes seconds and wakes nobody. The neck and arm openings are bound in soft fabric, not scratchy serged edges, and cut snug — the part that matters most for safe sleep.

Sizing: 0–6M (8–18 lb), 6–18M (18–28 lb), 18–36M (28–38 lb). Size to current weight. The 0–6M usually carries a baby through to the 4-month sleep regression; the 6–18M is usually the size your baby wears the longest.

Why waffle: The waffle-knit TENCEL™ Lyocell shell adds loft and traps warmth against the skin, so a cold-room bag stays warm without adding bulk — the same fiber and the same safe-sleep cut as our 1.0 TOG bag, just built for a colder room.

Gentle on sensitive skin and the planet, TENCEL™ Lyocell contains biodegradable fibers made from responsibly sourced eucalyptus tree pulp. It's made using a closed-loop production process where 99.5% of the solvents are reused during manufacturing, helping to minimize waste.
