Baby Sleep Bag 2.5 TOG in TENCEL™ - Hedgehog Forest
Buy Any 3 & Save 10%
When the nursery dips cold, this is the bag that replaces the blanket you're not allowed to use.
Mommy-and-baby hedgehogs and bunnies in a ditsy floral — calm bedtime.
This is the winter weight, built for a cold nursery between 61 and 68°F. When a 1.0 TOG stops being enough on the coldest nights, this is the bag that holds the warmth in without a loose blanket.
Material. A TENCEL™ Lyocell shell over a fuller layer of DuPont™ Sorona insulation, a plant-based fill that holds real warmth without the bulk of a padded blanket. TENCEL™ is Lenzing's wood-pulp fiber, spun in a closed-loop process and certified to OEKO-TEX Standard 100.
Why most brands skip this weight. A true 2.5 TOG is harder to make than a padded 1.0, so most premium lines stop at the lighter weight and leave cold nurseries to a loose blanket. This one is built for the 61–68°F room, so the blanket stays out of the crib.
The print. Ivory ground with a delicate mauve and burgundy ditsy floral, with mommy-and-baby hedgehogs and mommy-and-baby bunnies tucked into the foliage.
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.
Adjacent TOGs in the same print. Room warmed up to 69–75°F? The 1.0 TOG TENCEL™ Sleep Bag in Hedgehog Forest is the year-round weight. For warm summer nurseries above 75°F, the 0.5 TOG Muslin Sleep Bag.
Sizing. 0–6M (8–18 lb), 6–18M (18–28 lb), 18–36M (28–38 lb). Always size to weight, not age. Loose shoulders are a safety issue overnight.
Care. Machine wash cold and tumble dry low. Don't bleach, and don't iron the printed areas. TENCEL™ keeps its smooth face through the twice-or-thrice-weekly wash a baby's wardrobe demands.
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.
Common questions
When is a 2.5 TOG sleep sack the right choice?
When the nursery sits between 61 and 68°F overnight — cold-snap winter, drafty older homes, basement bedrooms. Below 61°F you're past sleep-sack territory and into raising the thermostat.
Will a 2.5 TOG be too warm for an average winter nursery?
If your nursery sits at 69–75°F overnight in winter, the 1.0 TOG TENCEL™ is the right weight. The 2.5 TOG is for genuinely cold rooms. Doubling a sleeper under a 1.0 TOG is also a common winter solution — but that can actually overheat your baby faster than a single 2.5 TOG bag would.
What is DuPont™ Sorona insulation?
Sorona is a plant-based polymer fiber DuPont produces from corn-derived feedstock. It traps warmth without bulk, so a 2.5 TOG sleep bag doesn't feel like a winter parka on a six-month-old. It also keeps its loft through wash cycles longer than polyester batting.
