What to Look for When Choosing the Best Baby Sleep Bags

As you compare options, consider these key factors:

1. Fabric & Breathability

Choose materials suited to your baby’s skin and nursery temperature. Muslin (0.5 TOG) offers soft, breathable everyday comfort, while TENCEL™ (1.0 & 2.5 TOG) provides ultra-soft comfort for sensitive skin in cooler settings.

2. TOG Rating

TOG measures insulation. Having access to multiple TOG levels allows for better year-round comfort.

3. Ease of Changes

Two-way zippers make diaper changes quicker and less disruptive during nighttime wake-ups.

4. Longevity & Washability

Frequent laundering is inevitable. Durable stitching and high-quality fabrics help maintain shape and softness over time.

5. Timeless Design

Some prints feel short-lived. Modern, coordinated styles—often found in thoughtfully designed collections—can grow with your child and complement changing nursery décor.

Frequently Asked Questions
