Sitka Men's Boreal AeroLite Bib

The Boreal Bib Pant is our warmest Waterfowl bottom, ideal for extended exposure to the most extreme conditions. Paired with the Boreal Jacket, it locks you into a 2-layer GORE-TEX® vault filled with the world’s first water-repellent hybrid down insulation, creating a walking sleeping bag that's 100% waterproof.
