The Burton Men's AK 3L Freebird Gore Tex Bib Pant offers ultimate protection from the deepest powder on the planet with its bib style design and legendary Gore Tex 3 layer membrane. The Freebird is fully sealed with Gore Seam tape to prevent moisture from sneaking through the pant's seams when you're riding in chest deep snow. The Freebird is incredibly lightweight for maximum comfort and efficiency when you're earning your turns in the backcountry and riding demanding lines. Gore Tex stretch panels along the upper chest and back promote freedom of movement needed for skinning, hiking beyond the resort, and sledding into hard to reach zones. The pant's AK fit uses engineered articulation to naturally move with your body, also allowing enough room underneath to fine tune your level of insulation. Keeping you from soaking in perspiration, the pant's 70D Gore Micro Grid backer actively pulls moisture off your skin to better regulate your body temperature. Zippered inseam and outside vents channel cool outside air over your lower body and legs when you're slogging uphill or riding under the warm spring sun. Another well designed feature is the large chest pocket that's accessible through any AK Jacket's underarm vents. This gives you grab and go convenience without slowing you down on fast paced missions.
