1.0 TOG Sleep Wear

1.0 TOG is built for 69–75°F nursery temperatures overnight — the most common US bedroom range. It's the year-round weight for most households.

For sleep bags that get washed weekly, yes. TENCEL™ Lyocell holds its surface and hand through fifty wash cycles; bamboo rayon pills and thins by month six. The first-touch test favors bamboo rayon; the durability test favors TENCEL™.

Match the under-layer to the room temperature within the 1.0 TOG band. Short-sleeve at 74–75°F, long-sleeve at 70–73°F, sleeper at 69–70°F.

Yes — "1 TOG" and "1.0 TOG" describe the same weight. Some brands use the integer form; others use the decimal form for clarity. The TOG rating is the same.

Sleep bags are sized by weight. The 0–6M fits 8–18 lb, the 6–18M fits 18–28 lb, and the 18–36M fits 28–38 lb. Most babies stay in the 6–18M for 8–12 months. When the baby is walking confidently in the crib (12–15 months), most families switch to a 1.0 TOG sleepsuit with separated legs.
