Technology and performance were top of mind when designing our Original Performance Mattress Pad. Starting from the surface, we combined our breathable, moisture-wicking Original Performance fabric with hypoallergenic CoolX fiber fill technology to keep you cool and to complement the other layers of your cooling Sheex Performance Sleep System. The unique shape of the hollow CoolX technical fibers prevents heat from accumulating in the material surrounding the body. This technology is designed to keep you cool and dry throughout the night by pulling moisture away from your body and enhancing moisture evaporation. Cool comfort for better sleep. Let Sheex own the night, so you can own your day.
