Combining 380 pairs of premium cooling particles and high-speed brushless motors, it delivers 1.5x wind speed and drops temperatures 4°F further than previous max settings (reaching an icy 22°F below ambient). Whether you're at a scorching MLB stadium, a humid construction site, or recovering from a gym session, 2S Pro provides the ultimate "Cold Compress" effect to keep you sharp and composed.
• -[PATENTED DUAL-AXIS: A TAILORED FIT] No more "one-size-fits-none."
