800 Down Fill

Certified 800+ Fill Goose Down bags are constructed with the following features:

Nautilus Hood: the same construction as our 8000m jacket hood, a 3D hood that
wraps around your head and reduces heat loss.
Hood Muff: creates a warm down gasket around your face, keeping the drawcord
away from the face.
Stretch Tricot Baffles: allow the bag to be stuffed and unstuffed without tearing the baffle material.
Trapezoid Foot box: matches the shape of your feet, wider in the toe area and narrower in the heels.
Down Fill Oversized Draft Tube: eliminates cold spots
Zipper guard: keeps the draft tube fabric from getting caught in the zipper
Ground Level Seams: top layer wraps fully around the body creating a warm layer of down.
