Emergency pull-on waterproof pant made from GORE-TEX® fabric with Paclite® technology. Reinforced hem and insteps are abrasion-resistant and durable N150p-X GORE-TEX® fabric. Lower leg zipper accommodates boots. Light, ergonomic and compact, it is designed for use when the weather takes a sudden turn for the worse.


The minimalist design helps maximize packability and reduce weight without sacrificing key features. Reinforced in key wear areas, articulated knees and a gusseted crotch provide freedom of movement, while WaterTight® lower leg zippers help accommodate boots.


N40r GORE-TEX® fabric with Paclite® technology is a very lightweight and compact waterproof/breathable fabric. Highly packable, it features a mini-ripstop face for increased tear strength. High-wear areas at the instep, lower leg and cuff are reinforced with a heavier weight, more durable N150p-X GORE-TEX® fabric.


Subtle, thoughtful construction details help shed grams. Careful design allows for minimal seam allowances that reduce unneeded material and minimize wear and chafing. Key wear areas are reinforced for extended durability.
