Nearly 40 years ago, I purchased a Trailwise (Berkeley, Ca) sleeping bag with 10 inches of loft (As I recall, it was approximately $300, alot of money in those days). After a successful ascent of Denali, I have been using it as a comforter ever since. The baffles have deteriorated over the many years, but the prime goose down still keeps the heat in! What is the life-span of down? Is there a way to repurpose the down? Seems a pity to throw it in the trash. I live in the Bay Area and would be delighted to pay someone to fabricate a his and hers down vest!
