Sleep Sack TOG Chart 2025: Parent’s Guide to Temperature

As a new parent, you’ve probably heard about sleep sacks — they’re a popular choice for safer sleep. But there’s one detail that often gets overlooked: TOG ratings. Simply put, a sleep sack TOG chart is like a cheat sheet that helps you pick the right sleep sack thickness based on your baby’s room temperature. It’s an easy way to make sure your little one stays safe, cozy, and not too hot or too cold while sleeping.

Why does this really matter? Well, unlike adults, babies can’t regulate their body temperature very well. If they’re dressed too warmly or not warmly enough, it can mess with their sleep — and even their safety. If you’re setting up your baby registry, don’t miss our step-by-step Amazon Baby Registry Setup Guide.

What Does TOG Mean in Sleep Sacks?

If you’re shopping for a sleep sack, you’ve likely come across the term TOG — but what does it mean? TOG, which stands for “Thermal Overall Grade,” is a standard measurement that indicates how much warmth a fabric provides. In other words, the higher the TOG rating, the warmer the sleep sack will be. For more details, you can also check the official HALO Sleep Sack TOG Chart.

How Does the TOG Rating Sleep Sack Chart Work?

To make things easier for parents, most brands offer a TOG rating chart that shows which sleep sack pairs best with different room temperatures. For example, a 0.5 TOG sleep sack is great for warm summer nights, while a 2.5 TOG is better suited for chilly rooms or colder seasons. That way, you can easily choose the right sleep sack based on the weather — or simply how warm or cool your home usually is. Planning a baby shower?

By paying attention to the TOG rating and using the chart as a simple guide, you’ll be making safer, smarter choices for your baby’s sleep environment every time.

1.5 TOG Sleep Sack Chart — When to Use It

Most TOG charts highlight popular ratings like 1.0 TOG or 2.5 TOG, but some brands also offer a 1.5 TOG sleep sack — a great option for those tricky in-between temperatures. So, when’s the right time to use it?

Ideal Room Temperature for 1.5 TOG Sleep Sacks

A 1.5 TOG sleep sack is usually recommended for room temperatures between 18°C and 21°C (64°F – 70°F). It’s a great pick for that cooler spring or fall nights — or for homes that tend to stay a bit chilly with air conditioning.

Simply put, it’s the perfect middle ground when a 1.0 TOG feels too light and a 2.5 TOG feels a bit too heavy.

Difference Between 1.0 TOG and 1.5 TOG Sleep Sack Chart

• 1.0 TOG: Best for moderate temperatures (21°C – 23°C / 69°F – 73°F), often paired with lighter pajamas.
• 1.5 TOG: Better suited for slightly cooler environments (18°C – 21°C / 64°F – 70°F), may require layering with long-sleeve pajamas.

Therefore, if you find your baby waking up chilly in a 1.0 TOG, but overheating in a 2.5 TOG, the 1.5 TOG might be the perfect middle ground for year-round comfort.

Complete TOG Chart for Sleep Sacks: From 0.5 to 3.5 TOG

Choosing the right sleep sack starts with knowing the TOG rating — and how it matches your baby’s room temperature. Below is a simple breakdown of common TOG ratings, so you can easily decide which sleep sack works best for each season.

0.5 TOG Sleep Sack Chart — For Warm Weather

Perfect for hot climates or summer months, a 0.5 TOG sleep sack is lightweight and breathable. It’s ideal for room temperatures around 24°C – 27°C (75°F – 81°F).

• Recommended Sleepwear: Short-sleeved bodysuit or diaper only.

1.0 TOG Sleep Sack Chart — For Mild Temperatures

A 1.0 TOG sleep sack offers a bit more warmth, making it suitable for spring, fall, or air-conditioned rooms at 21°C – 23°C (69°F – 73°F).

• Recommended Sleepwear: Short- or long-sleeved onesie or light pajamas.

2.5 TOG Sleep Sack Chart — For Cooler Nights

• Recommended Sleepwear: Long-sleeve onesie with footed pajamas or layers as needed.

3.5 TOG Sleep Sack — For Very Cold Climates (Optional)

Although not commonly used, a 3.5 TOG sleep sack is designed for very cold rooms — typically those below 16°C (61°F).

• Recommended Sleepwear: Several warm layers underneath. It’s always wise to check with your pediatrician to make sure you’re using it safely.

In short, whether it’s a warm summer night or a chilly winter evening, this complete TOG chart gives you an easy reference for dressing your baby safely and comfortably — all year round.

Understanding Sleep Sack TOG Chart: Celsius & Fahrenheit

When you check a sleep sack TOG chart, you’ll often see room temperatures listed in both Celsius (°C) and Fahrenheit (°F). It’s good to know how to read both — especially if you’re looking at charts from international brands.

How to Read the Sleep Sack TOG Chart: Celsius vs. Fahrenheit

Most TOG charts pair each rating with a recommended room temperature range. Some brands use Celsius, others use Fahrenheit, depending on where they’re based. That’s why it’s helpful to be familiar with both scales when choosing the right sleep sack for your baby.

For example:

• 1.0 TOG may be listed for 21°C – 23°C (69°F – 73°F)
• 2.5 TOG may be listed for 16°C – 20°C (61°F – 68°F)

In short, always double-check the temperature scale on the chart before making your choice.

Quick Temperature Conversions for Parents

Here’s a simple guide to convert Celsius to Fahrenheit:(°C × 1.8) + 32 = °F

Tip: Keep a quick-reference chart handy or bookmark a temperature converter app — it’ll save you from second-guessing your sleep sack choice later.

In the end, knowing both Celsius and Fahrenheit helps you confidently follow any TOG chart, no matter if the brand or where it’s from.

Safety Tips & How to Choose the Right Sleep Sack

When it comes to your baby’s sleep, safety is always the top priority — and choosing the right TOG rating plays a big role in that.

Why the Correct TOG Rating Matters

Choosing the right TOG sleep sack helps your baby stay at a healthy, comfortable body temperature — and that’s key to both safe sleep and better rest. Overheating is a known risk factor for sudden infant death syndrome (SIDS), so it’s important to choose a sleep sack that fits the room temperature.

Also, how you layer your baby’s sleepwear underneath the sleep sack can make a big difference in keeping them safe, snug, and comfortable all night long. For more insights on what TOG ratings mean, check out this helpful article from Love to Dream.

The TOG Chart Is a Helpful Guide — Not a Strict Rule

While the TOG chart is a great starting point, remember — it’s a guide, not a hard rule. Every baby is different, and factors like metabolism, room insulation, and sleepwear layers can affect comfort.

So, how can you tell if your baby is comfortable?  

• They feel their chest, neck, or back of the neck feel warm, not hot or sweaty.
• Adjust layers as needed, based on your baby’s cues.

In summary, use the TOG chart as a helpful reference, but trust your instincts and always monitor your baby’s comfort during sleep.

Layering helps keep your baby comfortable and safe during sleep. Use the TOG value as a guide:

• In cooler rooms, choose a higher TOG sleep sack and add a lightweight layer underneath.
• In warmer conditions, opt for a lower TOG sleep sack temperature chart with minimal layers.
• Avoid overdressing, as overheating increases the risk of SIDS.

Always check your baby’s temperature to ensure they are cozy yet safe! For another reference, you can explore the Newton Baby TOG Chart to better understand sleep sack warmth guidelines.

Choosing the Best Materials for Baby’s Sleepwear

Select soft, breathable, and hypoallergenic fabrics to keep your baby comfortable and safe. Great options include:

• Cotton and Bamboo – Gentle, breathable, and moisture-wicking.
• Microfleece and Wool – Warm yet breathable for cooler nights.
•  Avoid synthetic fabrics, as they trap heat and moisture, increasing the risk of overheating.

Avoiding Overheating

Overheating can increase the risk of SIDS and make sleep uncomfortable. Keep your baby safe with these tips:

• Dress your baby according to the TOG sleep sack chart and room temperature.
• If necessary, use an air conditioner or fan to ensure enough ventilation.
• Steer clear of bulky blankets that obstruct airflow.
• Look for indications of warming on your baby’s neck or chest.

Your kid will be safe and comfy all night long if you use the appropriate TOG rating.

Tips for Dressing Your Baby in Different Weather

• IN HOTTER WEATHER, dress your baby in cotton which is light and breathable. Artificial a one-time or light sleep is enough. Keep them shaded and hydrated.

• USE LAYERS IN COLD WEATHER: Wear an insulated jacket, hat, and gloves after beginning with a onesie and adding a top with sleeves and pants. To keep your baby warm, use materials such as down, fleece, or wool.

• RAINY WEATHER: Dress your baby in breathable, waterproof clothing, including a waterproof raincoat or rain suit. To prevent them from getting wet but not overheating, select materials such as Gore-Tex.

• WINDY WEATHER: Dress in wind-resistant clothing like polyester or nylon and dress up in warm clothes. Use a headscarf or balaclava to add extra coverage and cover the face and ears of your child with a hat.

• SPRING AND FALL: To accommodate fluctuating weather, layer-dress your baby. Use a breathable fabric such as cotton or bamboo for the base layer, and if it is needed, supplement with a jacket or sweater. Keep a blanket or backup layer handy in case of sudden changes in temperature.
