1.0 TOG Guide 🌙

If you've started shopping for sleep sacks, you've probably run into a mysterious little number: TOG. What does it mean, why does it matter, and why does everyone seem to be talking about the 1.0 TOG? We're breaking it all down so you can pick the perfect sleep sack for your little one without the guesswork.

And if you haven't met her yet, say hello to our Farm Fresh Sleep Sack in 1.0 TOG 🚜 — chickens, tractors, barns, and all the buttery-soft bamboo goodness your baby deserves.

What Is a TOG Rating, Anyway?

TOG stands for Thermal Overall Grade, and it's simply a way of measuring how warm a piece of sleepwear or bedding is. The higher the TOG number, the warmer (and cozier) the fabric. The lower the number, the lighter and more breathable it is.

Since babies can't regulate their own body temperature the way we can, TOG ratings take the guesswork out of dressing them for sleep. Instead of wondering "is this too warm? too light?", you can simply match the TOG to your nursery's temperature and know your little one is set up for safe, comfortable sleep.

Sleep sacks typically come in a few TOG levels:

• 0.5 TOG – lightest option, for warm rooms
• 1.0 TOG – the year-round sweet spot for moderate rooms
• 2.5 TOG – heavier, for cooler rooms and colder months

Why a 1.0 TOG Is Ideal for Summer (and Beyond)

Here's the golden rule: TOG should be chosen based on your nursery temperature, not the weather outside. If your baby's room sits somewhere in the moderate range — generally around 69°F to 73°F — a 1.0 TOG sleep sack is right at home.

That makes it a favorite for summer, when nurseries tend to run warmer and heavier layers can lead to overheating. Overheating isn't just uncomfortable for babies — it's also something pediatricians ask parents to be mindful of when it comes to safe sleep, so choosing the right TOG for the room (rather than just "what season it is") really does matter.

A 1.0 TOG sleep sack strikes that just-right balance: warm enough to replace a loose blanket, light enough to keep your little one from overheating on a warm summer night. It's breathable, layer-friendly, and honestly? It just makes bedtime simpler.

Quick tip: always check the back of your baby's neck or chest (not their hands or feet — those are naturally cooler!) to see if they feel just right, too warm, or too cool. It's the easiest way to know if you've nailed the TOG.

Why Bamboo Fabric Is a Great Choice for Babies 🌿

We build our sleep sacks with our Signature BamBeanie™ Bamboo Viscose Fabric, and once you feel it, you'll understand the hype. Here's why bamboo earns its spot as a nursery favorite:

It's incredibly soft. Bamboo viscose has a buttery, silky-smooth feel that's gentle on even the most sensitive baby skin — no scratchy tags or stiff seams here.

It's a temperature regulator. Bamboo fabric breathes. It helps keep babies cool when it's warm and cozy when it's cool, which is exactly why it pairs so perfectly with a 1.0 TOG for year-round wear.

It's clean by nature. We use sustainable bamboo that's free of harsh chemicals and isn't treated with flame retardants — better for your baby, and better for the planet.

It holds up wash after wash. Our bamboo fabric keeps its shape, softness, and color through countless trips in the washer and dryer, so it stays just as snuggly at month twelve as it was on day one.

FAQs

What does TOG stand for? Thermal Overall Grade — a rating system used to measure how warm sleepwear and bedding are.

Is a 1.0 TOG good for summer? Yes! A 1.0 TOG is ideal for moderate room temperatures (roughly 69–73°F), which makes it a great year-round choice and a summer favorite in air-conditioned nurseries.

What should my baby wear under a 1.0 TOG sleep sack? This depends on room temperature and your baby's comfort — many parents pair it with just a diaper or a light onesie in warmer rooms. When in doubt, check the back of your baby's neck to gauge their temperature.

Why is bamboo fabric better than cotton for baby sleepwear? Bamboo viscose is softer, more breathable, and naturally temperature-regulating, which helps prevent overheating — a key part of safe sleep.

Can I use a 1.0 TOG sleep sack all year? In rooms that stay in the moderate range, absolutely. It's one of the most versatile TOGs out there, which is why it's such a nursery staple.
