Buying Guide: Key Considerations For Summer Sleep Sacks

- Mobility and Hip Development: Look for roomy hips and leg openings so babies can move without kicking off the sack, promoting healthy hip development.
- Zippers and Safety: Prefer two-way zippers with top covers or zipper guards to protect delicate skin and ease diaper changes.
- Growing With Your Child: Adjustable lengths or multi-size options extend use across several months as your child grows.
- Maintenance: Machine washable fabrics are convenient, but some muslin or bamboo blends may require gentler care to extend life.
