1 / 5Best for: Sensitive skin, hot sleepers, TOG-matching households
The buttery cult favorite — bamboo rayon so soft parents buy matching pajamas, with real TOG discipline across the line.
Kyte built a parenting cult on one material: bamboo-derived rayon that stays cooler and dramatically softer than cotton, in a sleep bag line with honest TOG tiers (0.5 summer, 1.0 year-round, 2.5 winter) and a double zipper that opens from the bottom for changes. The 1.0 is the year-round default. It's the sack babies with eczema or sensory sensitivity tolerate when cotton gets scratched away — at more than twice the Beekeeper's price, and the delicate fabric wants gentler wash cycles.

The rayon weave moves moisture faster and feels cooler on contact — sweaty-headed babies wake less soggy. It's a real difference, not marketing, though the fiber is technically rayon derived from bamboo.
For a baby with eczema, night sweats, or texture sensitivity — yes, immediately. For a happy cotton sleeper, the Beekeeper rotation is the smarter spend.
It pills under hot-dryer abuse. Gentle cycle and hang-dry keeps it buttery for a year-plus; treat it like knitwear, not like a burp cloth.
1.0 for rooms 69-73°F (most homes year-round), 0.5 for summer/warm climates, 2.5 for rooms under 68°F. Kyte's TOG discipline across the line is exactly what the category should do.
