Why Climate-Specific Gear Matters
Your baby’s comfort and safety depend heavily on appropriate clothing and gear for your local climate. Babies cannot regulate their body temperature as effectively as adults, making climate-appropriate gear essential for their health and well-being. Choosing the right products for your climate ensures better sleep, safer outdoor activities, and peace of mind for parents.
Key Considerations
- Babies overheat easily in hot weather and need breathable fabrics
- Cold weather requires proper layering and warm sleep sacks (1.0-2.5 TOG)
- Temperature regulation affects sleep quality and safety
- Climate impacts outdoor activities and travel gear choices
- Seasonal changes require adaptable gear that works year-round
- TOG ratings determine warmth level in sleep sacks
Understanding TOG ratings helps you choose the right sleep sack for your climate. TOG (Thermal Overall Grade) measures thermal insulation:
- 0.5 TOG: Lightweight for hot weather (75-81°F room temperature)
- 1.0 TOG: Standard for mild weather (68-75°F room temperature)
- 2.5 TOG: Heavy for cold weather (61-68°F room temperature)

Cold Weather Safety
- Maintain room temperature: Keep room temperature between 68-72°F for sleep
- Avoid overheating: Don’t over-layer—check baby’s temperature regularly
- Check for cold hands and feet: Cold extremities are normal, but cold torso indicates under-dressing
- Use safe heating methods: Avoid space heaters near baby; use central heating
- Monitor humidity levels: Use a humidifier if air is too dry
- Proper layering: Onesie + light pajamas + sleep sack (1.0-2.5 TOG)
- Check temperature: Feel neck or torso—should be warm and dry, not sweaty
Safety First
Always prioritize your baby’s safety over convenience. When in doubt, err on the side of caution with temperature regulation and weather protection. Check your baby’s temperature by feeling their neck or torso—it should feel warm and dry, not sweaty or cold. If you’re unsure, it’s better to add or remove a layer than risk overheating or cold exposure.

Hot Weather (75-81°F Room Temperature)
- Sleep Sack: 0.5 TOG (lightweight cotton)
- Underneath: Just a onesie or light cotton pajamas
- Outdoor: Lightweight, breathable clothing with sun protection
- Carrier: Mesh construction for airflow
Cold Weather (61-68°F Room Temperature)
- Sleep Sack: 1.0-2.5 TOG (merino wool or fleece)
- Underneath: Onesie + light pajamas
- Outdoor: Warm layers with proper insulation
- Check Temperature: Feel neck or torso (should be warm and dry, not sweaty)
Mild Weather (68-75°F Room Temperature)
- Sleep Sack: 1.0 TOG (standard)
