Many performance-cooling comforters rely on synthetic nylon and spandex. Our cooling fabrics are woven from 100% TENCEL™ Lyocell, a cellulosic fiber derived from responsibly sourced wood—and still achieved a lab-tested Qmax of 0.405 W/cm².
- 300 thread count TENCEL® shell with TENCEL® fiber fill.
- Fabric and fill are fully biodegradable.
- Examined by hand for product defects.
- Loops in every corner for duvet cover ties.
Independent Testing & Research:
Fiber smoothness. Under microscopy, lyocell has a nearly circular cross-section and a smooth, cylindrical surface — without the striations, twists, or ridges of cotton and linen (published fiber science, ScienceDirect: Lyocell Fiber). A smoother surface means less friction against the skin, which is what registers as softness.
Skin health. Researchers Love and Nedorost found significant preference among subjects with sensitive skin for lyocell (vs cotton) for its softness, temperature control, moisture control, and wrinkle resistance (published in Dermatitis, Vol 20, Issue 1).
Cool touch. Intertek (FTTS-FA-019) measured a Qmax of 0.405 W/cm² — the higher the Qmax, the faster heat moves from skin to fabric. Most performance-cooling sheets rely on synthetic nylon and spandex. Ours are woven from 100% TENCEL™ Lyocell — a cellulosic fiber from responsibly sourced Eucalyptus — and still test cool.
Moisture management. In peer-reviewed testing at 20°C and 60% humidity, lyocell absorbed 9.23% of its weight in moisture versus cotton's 5.54% — about 67% more. (A controlled fiber test, not a finished-sheet measurement.)
Durability. Hohenstein (ASTM) recorded first thread breakage at 18,000 abrasion rubs (D4966-22), a 4.0–5.0 pilling resistance (D3512), and tear strength of 10.4 lbf warp / 6.4 lbf weft (D1424).
Clean. Certified to OEKO-TEX® STANDARD 100 Class I — the strictest class, held to the same standard as textiles for babies under three.
