Buying Guide — Key Purchase Considerations
- Fabric and skin safety: Look for 100% cotton or bamboo blends with breathable, hypoallergenic properties. Ensure fabrics meet safety standards (e.g., GOTS where noted).
- Size and growth room: Choose based on current height and anticipated growth. Split-leg designs help accommodate growing toddlers who are still learning to walk.
- Temperature and Tog rating: A 0.5 Tog is common for warm rooms or summer nights; higher Tog is not typical for sleep sacks with legs and may cause overheating.
- Mobility features: Prioritize a design with a split-leg or adjustable ankle bands to prevent tripping and to support safe movement.
- Ease of nighttime changes: Hidden or double zippers are preferable to minimize skin contact during diaper changes.
- Care and maintenance: Check washability and fabric resilience; durable zippers are important for long-term use.
