The science
2×
faster heat transfer than cotton
Arc-Chill is a mica-infused fiber engineered in Japan. Its Q-Max rating above 0.4 — an independent lab standard — means it conducts heat away from your skin roughly twice as fast as ordinary cotton. No electricity, no gels, no refills. The physics is in the fabric.

One blanket, two seasons
Cool side for July.
Cotton side for January.
Flip it and the breathable cotton waffle side becomes a regular cozy blanket. You feel covered, never smothered — featherlight in summer, warm enough for winter.
