JACK WOLFSKIN FROSTFIRE REGULAR

A high-performance expedition bag with an insulation rating that makes it suitable for use in double-digit minus temperatures. Thanks to the premium quality, high-loft 90/10 goose down (700+ cuin) fill, the extremely light shell fabric and the intelligent chamber design, we have managed to achieve this amazing spec at a weight of just 1700g.

To meet the requirement for different levels of insulation at different parts of the body, the bag benefits from extra fill in hood, torso and foot sections. The ingenious combination of trapezoid, vertical and sidewall fill chambers allows the down to achieve maximum loft and optimal distribution, which prevents cold bridges and associated heat loss.

The FROSTFIRE is equipped with a thermal collar that can be cinched in snugly around the shoulders.
