The Kyte Baby Sleep Sack in Fog is the boutique-curated safe sleep essential our team recommends to every new family — a cozy, wearable alternative to loose blankets in the crib, made from the same silky bamboo rayon that Kyte Baby is known for. The soft, muted Fog colorway pairs beautifully with modern neutral nurseries, and the 1.0 TOG weight hits the sweet spot for year-round use in a temperature-controlled nursery.
What 1.0 TOG Means for Your Nursery
TOG measures how quickly a fabric retains heat — the higher the number, the warmer the layer. At 1.0 TOG, this sleep sack is ideal for nursery temperatures between 21–23°C / 69–73°F, making it a reliable year-round mid-layer that works across seasons without overheating. When in doubt, dress baby in a single base layer underneath and adjust from there.
Bamboo Softness, Double-Zipper Convenience
The exterior is 97% rayon from bamboo with 3% spandex for gentle stretch, filled with 100% polyester for consistent warmth without bulk. A double zipper opens from both the top and bottom for quick, low-disruption diaper changes — no need to fully remove the sack or wake a sleeping baby in the process.
