The GORE-TEX membrane is created as a series of pores. Each pore is 20,000 times smaller than a water drop, yet large enough for vapor to pass through. This creates the ultimate membrane for keeping the inside of your garment dry while still allowing moisture and perspiration to pass through, effectively regulating your body temperature while keeping you comfortable inside your jacket or pants. GORE-TEX guarantees you will stay dry and warm in any condition, for the life of your garment. All GORE-TEX fabrics are bluesign® approved, meeting the highest environmental standards.

The Original, Trademarked 3-in-1 Detachable Layering System. Since its inception decades ago, 686 SMARTY® 3-in-1 technology has set the integrated layering standard for the outerwear industry, adding premium versatility and value to jackets and pants. Every SMARTY® combination is specifically designed so that the shell and detachable liner work in unison to provide the ultimate experience, versatility, and value. You can wear your garment in multiple ways: 

• Shell + detachable layer for integrated insulation on the coldest of days. 
• Shell only for moderate days. 
• Detachable layer only for more casual occasions.
