Buying Guide
What to consider when choosing a 0.5 tog sleep sack:
- Fabric and skin sensitivity: Opt for organic cotton for sensitive skin, or bamboo blends for enhanced breathability.
- Safety features: Look for two-way zippers, zipper guards, and neck/arm openings that minimize skin irritation and ensure a snug fit to reduce the risk of kicking off the sack.
- Age and size range: Some sacks are designed for newborns, others grow with infants into toddlers. Check size guidance to avoid overwrapping or excessive looseness.
- Diaper changes: A bottom-access zipper simplifies nighttime changes without fully undressing the baby.
- Care and durability: Machine-washable fabrics with durable seams help withstand frequent laundering common for wearable blankets.
- Climate suitability: 0.5 TOG works well in warm rooms; consider layering if the sleeping environment varies widely.
