0.5 TOG

Use a 0.5 TOG sleep bag in warm rooms — typically 74-78°F or higher — and during summer months. At these temperatures, a 1.0 TOG or 2.5 TOG would trap too much heat and risk overheating, which is itself a sleep-safety concern. For a baby in a 0.5 TOG, dress them in a single layer underneath (a short-sleeve bodysuit is usually enough). Many parents keep both 0.5 and 1.0 TOG bags on hand and switch by season.

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.

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.

Touch the back of the baby's neck or chest (not hands or feet, which run cooler than core). Skin should feel warm and dry — not sweaty (too warm) or cool (too cold). Damp hair, flushed cheeks, or rapid breathing also signal overheating. If too warm, switch to a lighter TOG or remove a layer underneath; if too cold, add a layer underneath or move to a higher TOG. Most overheating risk comes from over-dressing under the bag, not the bag itself.

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.
