- Zipper design: A two-way zipper with interior zipper guards protects skin and enables easy diaper changes.

FAQ
- What exactly is TOG and why does it matter for summer sleeping sacks? TOG indicates thermal insulation. A lower TOG (0.3–0.5) is better for warm nights, helping to prevent overheating.
- Are wearable blankets safer than swaddles in summer? Wearable blankets reduce the risk of loose blankets and provide consistent warmth without restricting movement as babies grow.
- How should I choose the right size? Look at height-based sizing when available. A sack that’s too tight can be uncomfortable, while one that’s too loose may ride up and pose a safety risk.
- Can these sacks be washed in a standard machine? Most are machine washable, but check the fabric care label. Delicate cycles help maintain fabric softness over time.
- Is bamboo fabric better than cotton for summer? Bamboo is typically softer and more breathable, with good moisture-wicking properties, which can help keep a baby comfortable in heat.
- What are the safety reminders for a sleep sack? Ensure a proper fit, remove loose items from the sleeping area, and never add loose blankets on top of a sleep sack.
