why günamüna?
- Safety First, Always: Sleep easy knowing our bamboo baby sleep sacks are designed with your baby’s safety in mind. Each wearable blanket is rigorously tested by a leading JPMA-certified lab and trusted by Certified Pediatric Sleep Consultants—so you can feel confident your baby is sleeping safely and comfortably.

- Cloud-Soft Bamboo Comfort: Made from ultra-soft bamboo viscose fabric, our sleep sacks create a breathable microclimate against baby’s sensitive skin. This temperature-regulating bamboo fabric helps prevent overheating and sweaty discomfort that can interrupt precious sleep.
- Perfect Temperature Control: With multiple TOG-rated baby sleep sacks designed for different room temperatures, it’s easy to find the right warmth level for every season—helping baby sleep comfortably through the night.
sleep sacks
We believe better sleep should grow with your baby. Our baby sleep sacks and wearable blankets replace loose blankets with safe, wiggle-friendly warmth. Our thoughtfully designed bamboo baby sleep sack collection includes options for every stage of sleep development:
- Swaddle Sleep Sacks that recreate a cozy womb-like feeling to help calm startle reflexes and encourage longer sleep
- Transitional Swaddle Sleep Sacks designed for the “not quite rolling but almost there” stage as babies begin gaining mobility
- Sleeveless Sleep Sacks that provide lightweight warmth for warmer nights or naturally hot sleepers
- Long Sleeve Sleep Sacks that add extra coziness and warmth when room temperatures drop
- Footie Sleep Sacks that keep active little toes warm while allowing babies and toddlers to move freely
Available in multiple TOG-rated sleep sacks (0.5–2.5 TOG) to match different room temperatures and seasons. Our sleep sacks are designed to grow with your baby (from newborn to toddler) and are made from luxuriously soft bamboo viscose fabric that feels like a cloud against delicate skin.
Every günamüna sleep sack is OEKO-TEX® Standard 100 certified, ensuring no harmful substances: just breathable comfort that helps create the ideal sleep environment night after night.
TOG (Thermal Overall Grade) measures how warm a garment is. In baby sleepwear and baby sleep sacks, TOG ratings help parents choose the right warmth level so babies sleep safely and comfortably based on room temperature.
Use the TOG guide below to determine which TOG sleep sack is best for your baby’s sleep environment. These recommendations are based on the nursery temperature where your baby is sleeping.
At günamüna, we typically offer 0.5 TOG sleep sacks for warmer summer months, 2.5 TOG sleep sacks for cooler winter temperatures, and 1.0 TOG sleep sacks that work well year-round.
TOG Guide
0.5 TOG — 74–78°F / 23–26°C
1.0 TOG — 70–73°F / 21–23°C
2.5 TOG — 58–70°F / 15–21°C
