GFB HYBRID TMS Dual Port 15+ Subaru WRX / ForesterAll The Performance With The Noise! The Hybrid valve is back! In 1999, GFB's first Hybrid valve pioneered the dual port design, which was so successful the technology has since been adopted by most other brands.

These pillows are amazing. I absolutely love them. I’m going through menopause, so I’m constantly hot, then cold, then hot again. These pillows are truly cooling, and they make a huge difference. I’m a side sleeper, and they are incredibly comfortable. They’re worth every penny, and I highly recommend them to everyone.
