Babies still benefit from sleep sacks in the summer, but the choice depends on the room temperature and your baby's comfort. In warmer climates or during hot summer months, you can opt for lightweight, breathable sleep sacks or sleeveless ones to keep your baby comfortable and prevent overheating
The coolest TOG (thermal overall grade) rating for a sleep sack is typically 0.5 TOG or 0.2 TOG. TOG ratings indicate the warmth and insulation level of the sleep sack. A lower TOG means the sleep sack is lightweight and designed for warmer room temperatures or hot weather conditions. These summer-weight sleep sacks help keep babies cool and comfortable during the night without causing overheating.
The best material for a sleep sack is one that is soft, breathable, and hypoallergenic. Organic cotton is a popular choice as it is gentle on a baby's sensitive skin and allows for good airflow, preventing overheating. Bamboo fabric is another excellent option known for its softness, moisture-wicking properties, and eco-friendliness. Both materials are comfortable and safe for babies.
