Description

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 61–68°F 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.

Why We Love It

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 61–68°F nursery.

The Details

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.

Materials & Care

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.

94% TENCEL™ Lyocell, 6% spandex, Dupont Sorona® filling

This style was updated with a new fabric blend of 94% TENCEL™ Lyocell, 6% spandex.

Depending on color and size selected you may receive our classic blend of 68% TENCEL™ Lyocell, 26% organic cotton, 6% spandex.

Both versions meet our high standards for softness, breathability, and sustainability. If you have a specific preference or need help confirming the fabric composition of your size, feel free to contact our team.

FAQs

Why TENCEL™ for this sleep bag instead of muslin?

TENCEL™ Lyocell is a wood-pulp fiber spun in a closed-loop process. It pulls moisture off the skin quickly and stays soft and keeps its look through repeated washing, so we use it in our year-round 1.0 and 2.5 TOG sleep bags, the ones that get washed most. For the lightest warm-weather layers, you might want our products made with Tanboocel® Bamboo Viscose — like the 0.5 TOG sleep bags, swaddles, and crib sheets.
What TOG rating should my baby wear?

Match the TOG to the room. 0.5 TOG for 75–81°F. 1.0 TOG for 70–75°F, the most common nursery temperature in Canada. 2.5 TOG for 61–68°F cold nurseries. A nursery thermometer removes the guesswork.
What should baby wear under a 2.5 TOG sleep sack?

A short-sleeve bodysuit alone at the top end of the range (66–68°F), a long-sleeve bodysuit in the middle (63–66°F), or a sleeper plus socks at the coldest end (61–63°F). The TOG rating gives you the main warmth; what your baby wears underneath lets you fine-tune from there.
