Wave Construction offers the advantages of both traditional blanket and shingle construction with no significant increases in bag weight. Additional features of Wave constructed bags include:
• Nautilus hood: the same construction as our 8000m jacket hood, a 3D hood that
wraps around your head and reduces heat loss.
• SpiraFil insulation: a unique blend of 3 denier conjugated spiral hollow fibers for loft and 1 denier polyester fibers for warmth, softness and compressability
• Zipper guard: keeps the draft tube fabric from getting caught in the zipper
• Trapezoid foot box: matches the shape of your feet, wider in the toe area and narrower in the heels.
