Buying Guide
What TOG level should you choose? For cooler bedrooms, a 1.0 TOG is typically enough given a sleep sack’s breathability. In warmer rooms, a 0.5 TOG or lighter is preferable, while 1.5 TOG is more appropriate for cooler nights or air-conditioned spaces.
Which fabric is best? Bamboo viscose and rayon-from-bamboo blends are known for softness and moisture-wicking. These fabrics are generally gentler on sensitive skin compared to cotton blends, though cotton options can be better for babies with sensitive allergies.
What design features matter? Look for a tagless design to reduce irritation, a two-way zipper for quick diaper changes, and a zipper guard or protector to avoid skin contact with the zipper. A deeper neckline or adjustable features can improve safety and fit as your baby grows.
How should you size and fit? Sleep sacks should feel snug but not tight around the chest, with enough room for leg movement. Check the manufacturer’s size guidance for age ranges to avoid sleeves or legs riding up during sleep.
