Buying Guide: How To Choose The Right Sleep Sack
- Material safety and breathability: Prioritize breathable fabrics like cotton and bamboo viscose to reduce overheating and skin irritation. Look for GOTS or Oeko-Tex certificates when possible.
- TOG rating and temperature: TOG indicates warmth. For year-round use, choose 0.5 TOG for warmer months and 1.0 TOG or a version with wadding for cooler nights.
- Ease of diaper changes: Two-way zippers and zipper guards help minimize disruption. Ensure the zipper locks securely to prevent openings during sleep.
- Fit and mobility: Arm, neck, and leg openings should allow movement without letting the baby kick off the sleep sack. Hip-friendly designs support healthy development.
- Safety features: Avoid loose fabrics, ensure necklines are secure, and verify that materials are hypoallergenic and free from harmful substances.
- Cleaning and care: Check care instructions; some fabrics require gentle washing and air drying to maintain softness and shape.
