Wiley X XL-1 Gasket vs. Boss Gasket: Which Replacement Do You Need?
Both the XL-1 and Boss gaskets serve the same purpose—creating a foam seal that blocks dust, wind, and debris—but they're designed for different frame models in the Wiley X lineup. Here's how to choose the right replacement.
Frame Compatibility
The XL-1 gasket (model XLG) fits exclusively the Wiley X XL-1 Advanced frames, while the Boss gasket is designed for the Climate Control Boss model. These gaskets are not interchangeable—each is engineered to match the specific contours and mounting points of its corresponding frame. Always verify your frame model before ordering.
Design and Coverage
The Boss represents Wiley X's newer Climate Control series and features a high-wrap design with wider temples and more facial coverage, making it ideal for larger faces or those who want maximum protection. The XL-1 Advanced is part of the earlier generation with a slightly more compact profile. Both use removable ultra foam technology, but the Boss gasket benefits from updated materials that some users find more durable in wet conditions.
Price and Value
At $24, the XL-1 gasket is a straightforward OEM replacement for a proven design. The Boss gasket runs $21, reflecting its position in the current product line. Both offer excellent value for extending the life of your eyewear—replacing a worn gasket is far more economical than buying new frames.
Bottom line: If you own XL-1 Advanced frames, the XL-1 gasket is your only option and delivers reliable protection. If you're considering which Wiley X model to buy, the Boss offers more modern features and broader lens options, though the XL-1 remains a solid choice for those who prefer a less bulky profile.
