For hot sleepers the weight of a blanket is as important as the material it is made from. Yet most people focus entirely on the fiber type and ignore the fill weight.
Why Fill Weight Affects Sleep Temperature
Every gram of fill in a blanket creates insulation. The fill traps tiny pockets of air between the layers of fabric which act as an insulating barrier slowing the transfer of heat from inside the blanket to the outside air. The more fill the more insulation and the warmer you sleep. This is true regardless of what the outer fabric is made from.
The Target Weight Range for Hot Sleepers
For summer use target under 1.0kg for a queen size blanket. For shoulder season use 1.0-1.2kg is acceptable for most hot sleepers. Above 1.5kg for a queen size is likely to cause problems for any significant hot sleeper in weather above 18 degrees.
Recommendations by Weight
Lightest option: The Stillwell Cooling Blanket, thin and lightweight, ideal for very warm nights. See The Cooling Blanket here.
Best balance: The Stillwell Cloud at 0.75-1.0kg, lightweight enough for summer and substantial enough to feel like a proper blanket year-round. See The Cloud here.
The Bottom Line
For hot sleepers lighter is always better when the material quality is equal. If you are comparing two cooling blankets of similar fiber type and Q-Max always choose the lighter one.
