Frequently Asked Questions

What are the key features of the Stone Glacier Chilkoot 15 Degree Bag?

The Chilkoot 15 Degree Bag features 22 ounces of 90/10 grey goose down with 850+ fill power, a 15-denier Pertex Quantum shell, YKK zipper, and dimensions suitable for individuals up to 6'5" with shoulder, waist, and footbox measurements of 32", 24", and 18" respectively.

How does the Stone Glacier Chilkoot 15 Degree Bag perform in cold weather?

In practical use, the bag performs well, though in temperatures around 24 degrees Fahrenheit, additional insulation like a puffy jacket over the feet might be beneficial, especially if footwear has become wet. It's designed for cold weather but offers versatility through unzipping.

What is the significance of 'fill power' in sleeping bags like the Chilkoot?

Fill power indicates the loft and insulating capability of down. The Chilkoot's 850+ fill power signifies high-quality down that provides excellent warmth for its weight, making the bag lighter and more compressible than bags with lower fill power.

How water-resistant is the down insulation in the Stone Glacier Chilkoot bag?

Modern down insulation, especially when compressed, offers significant water resistance. The bag's down is treated, and even if exposed to moisture, it retains insulating properties unless fully submerged and fluffed, making it reliable in damp conditions.
