2.5 TOG

Use a 2.5 TOG sleep bag in cool rooms — typically 65-68°F — and during winter months in regions with cold nights. 2.5 TOG provides enough warmth that most babies need only a single underlayer (footed pajamas or long-sleeve bodysuit). For rooms below 65°F, layer a long-sleeve bodysuit + footed pajamas underneath; for rooms above 68°F, switch to a 1.0 TOG to avoid overheating.

Yes — sleep bags (also called sleep sacks) are the American Academy of Pediatrics-recommended alternative to loose blankets in the crib for infants under 12 months. The bag wraps around the baby like a wearable blanket and stays securely in place, removing the suffocation risk of loose bedding. Each Quince sleep bag is sized so the neck opening fits without slipping over the head, and the armhole openings are sized to prevent shoulders from sliding through.

A 2.5 TOG is too warm only if the room is above 68°F and the baby is dressed in multiple layers underneath. Overheating risk depends on TOG + room temperature + dressing combined, not TOG alone. Touch the back of the neck or chest to check — skin should feel warm and dry. If the baby is sweaty, the combination is too warm; switch to a lighter TOG or remove a layer underneath. In a 65-68°F room with a single underlayer, 2.5 TOG is in the safe range.

Bamboo viscose is a Lyocell-process fiber derived from bamboo pulp — naturally cool to the touch, breathable, and moisture-wicking. For sleep bags, bamboo viscose regulates temperature better than 100% polyester (which traps heat) and is gentler against skin than cotton (which can feel scratchy when slept on for hours). Quince uses bamboo viscose across the full TOG range so parents can choose by warmth rating rather than fabric type.

Quince sleep bags are sized by age range: 0-6 months, 6-18 months, 18-36 months, and 3-6 years. Each product page lists the exact sizing guide. Sleep bags are designed with growing room — most children wear each size for 6-12 months before sizing up. Sizing too large is the most common parent mistake; the bag should fit snugly enough at the chest that the baby cannot slip down inside.

Machine wash cold on a gentle cycle with mild, fragrance-free detergent (a baby-safe detergent is best for newborn use). Skip fabric softener and bleach. Tumble dry on low or hang dry. Run pieces through one extra rinse cycle for newborn use to remove all detergent residue. Bamboo viscose softens with each wash and holds up to the frequent laundering sleep bags require.
