Guohaoi’s Arc-Chill Cooling Blanket uses a specific type of nylon fiber engineered for heat transfer. The technical term for this is a Q-max value, which here measures above 0.5. In practice, that means the blanket actively pulls warmth away from your skin on contact. It doesn’t just feel cool initially; it sustains that sensation.

The 400-thread-count weave made from this cooling nylon is dense and smooth. This high thread count isn’t for luxury, but for function. It increases the fabric’s thermal capacity, allowing it to absorb more body heat before warming up. You notice it most on a warm night—the blanket stays neutral and dry, not trapping heat like cotton or microfiber.

At 50 by 70 inches, it’s a generous throw size, ideal for a single sleeper or draping over a couch. The grey color is neutral, and the bagless design means it arrives ready to use. Just know it’s a cooling blanket, not a weighted one. The focus is purely on temperature regulation, not deep-pressure comfort.
