Frequently Asked Questions
What TOG rating is best for summer nights?
For warm rooms (around 75–83°F / 24–28°C) choose a 0.5 TOG sleep sack; 1.0 TOG is acceptable if the fabric is very breathable (muslin or bamboo-rayon) and your nursery is cooler or air-conditioned.
Are bamboo-rayon sacks better for sweaty babies?
Yes — rayon made from bamboo is known for moisture-wicking and a cool hand, so it can help babies who sweat at night feel dryer and more comfortable than dense cotton.
How should a wearable blanket fit my baby?
The sleep sack should be snug at the neckline and armholes so fabric can't ride up, roomy through the hips and legs for natural movement, and the length should allow safe leg movement without excess fabric near the face.
