Buying Guide: Key Considerations For Choosing A 1 TOG Sleep Sack
- Materials: Pure cotton offers softness and breathability; blends (cotton/polyester) can add durability and shape retention.
- Fit: Look for a roomy but secure neck, and a design that prevents the baby from slipping into the sack while supporting hip development.
- Zippers: Prefer two-way zippers for easier nighttime diaper changes; check for zipper protectors to avoid chin irritation.
- Seasons and climate: A 1.0 TOG is generally suitable for moderate climates or air-conditioned rooms; layer as needed for cooler environments.
- Care and durability: Pre-shrinking and washable fabrics extend the product’s life; verify tumble-dry suitability and washing instructions.
