Got this great EB down parka on sale for $399. last month. The internal zipper baffle was barley insulated with some bonded synthetic.
!. seam rip the top 1″ of the zipper baffle tube
2. fill zipper baffle tube with 800 fill DWR down from “Ripstop by the Roll” (This meant stuffing loose down thru a funnel spout into the baffle tube and on down to the bottom of the tube and gradually filling up the tube.)
3. sew the tube top closed
4. shake and stroke the tightly bunched groups of down into an even distribution
Hey, it works very well. With my crude stuffing method I had to stuff the tube with likely 3 – 4 times as much as the factory would have used but it is nicely filled and will not collapse – period.
FUTURE MODS:
-> I’ll have my tailor sew a left side zipper tube on that I can also fill with down. This will give me double mating baffles like Patagonia uses on their GRADE VII and Fitz Roy parkas.
-> Next I may put a bit more down into the two upper sleeve baffles. I’ve got a gallon bag of it left!
-> I have a nice coyote fur ruff I got last month. I’ll modify the backing with stiffened cloth, sew Velcro on it and the mating soft side of the Velcro strip to the parka hood for a removable ruff.
When finished this parka will easily take me to -40 F. with proper clothing beneath it. I’ve experienced -40 F./C so I know what is needed for those temperatures.
