Marmot MemBrain®
MemBrain® fabric balances the best performance in waterproof, breathable fabric with excellent durability.
MemBrain® reduces internal condensation while increasing comfort by reducing the chilling effect caused by condensation build-up.
When used with insulated garments or sleeping bags, MemBrain® protects the insulation from harsh weather conditions.
600 Fill Down

Certified 600 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.
