The First Lite Boundary Stormtight Pant is the weatherproof, lightweight shell component of the First Lite Layering Kit. Using patented 37.5 Technology and the industry's best DWR and lamination, we combined custom-constructed fabrics made to First Lite's specifications to create the very best in foul-weather pants. The result provides unsurpassed protection against the harshest conditions Mother Nature has to offer. These lightweight 2.5-layer pants feature full-length zippers, reinforced knees and cuffs, and suspender loops for use with your First Lite suspenders. Paired with either our Vapor or SEAK Jacket, you can feel confident that you will be dry and protected from the harshest conditions you will encounter while forgetting they're in your pack on the way out. An important note about sizing: Please be aware that the Boundary Stormtight pants are designed to be worn over your Obsidians or Corrugates, thus are a roomy fit. Made with PFAS Chemicals
