The Spark SpIII is a model designed for sub-zero temperatures.
Perfect for winter missions where you want to reduce your luggage as much as possible.
The entire jacket has a box baffle structure that traps more down and eliminates cold spots.
This expedition-sized mummy type seat offers plenty of space.
Vertical baffles are placed above the torso to prevent the down from moving.
The half-length zipper has two sliders, making it easy to use and ventilation.
Ultra Dry Down is treated with a water-repellent coating to virtually eliminate moisture, which can have a detrimental effect on down.
