Buying Guide

What TOG Do You Need?

TOG measures insulation. For rooms around 68–72°F, 0.5–1.5 TOG is common. Heavier TOGs (2.0–3.0) are better for cooler rooms. Consider your climate and the baby’s room temperature when choosing a sleep sack.

How Should a Sleep Sack Fit?

Look for a snug but not tight fit at the chest with room for hip movement. A two-way or three-way zipper simplifies diaper changes. Arms-in, one-arm-out, or arms-out options help transitions as the baby grows.

Material and Breathability

Viscose and bamboo blends are soft and moisture-wicking, suitable for sensitive skin. Cotton is durable and breathable but may feel warmer in high temperatures. Ensure fabrics are free from harmful chemicals and labeled safe for babies.

Safety and Design Considerations

Choose products designed to replace loose blankets and promote back-sleep safety. Look for features like secure fasteners, non-irritating zippers, and hospital-grade endorsements when available. Avoid heavy embellishments that could irritate delicate skin.
