There have been some great threads in here relating to creating a down quilt. I'm trying to decide if I should take the plunge. In particular, I'm trying to decide if I should use the kit at thru-hiker.com, which contains 12 ounces of 900FP down and the Momentum fabric for the shell and liner. The kit costs $160, which appears to result in an ~20 oz. quilt that is good down to 30* (is that accurate?).
On the other hand, if I can source 800+FP down at around $6.50 an ounce and buy the fabric elsewhere, it might cost significantly less (around $100).
I need help with the following questions:
- How much down will I need to make a quilt that's good down to a conservative 25-30*?
- Is it better to buy the materials myself or just buy the kit from thru-hiker?
- Are there better materials that I can buy other than Momentum90 or Momentum55?
- Though I can't convert my existing 20* down bag, I'm willing to destroy it to get the 750+FP down inside, and I think there's about 16 ounces of it. It could save me $100 on down, which is worth it to me, but how much weight would I be adding at only 750+ instead of 900 for equivalent loft? I could also use leftover down to make a hat.
