M50 Down Max Pullover on 11/17/2013 15:26:55 MST Print View

I turned a blunder into an interesting jacket. I had originally made a primaloft pullover jacket based on an adjusted Kinsman jacket from gray M50. I washed this jacket in a washing machine. Even though I have done this with other primaloft MYOG items this jacket got wound around the agitator and the spin cycle left the inner primaloft shredded into clumps. I was close to throwing the jacket out when I got the idea to open the jacket up and see if I could redistribute the primaloft and sew it into mini chambers like a Patagonia Nano puff. Unfortunately the primaloft was too shredded. Since I have wanted to make a medium weight down jacket to use in cold temps I worked carefully to remove all the primaloft then sewed chambers for down and stuffed the jacket.

Here is a picture of the finished jacket. It has a double layer loft of of 2.75".

The new jacket I call the LytW8 Down Max Pullover. It is made from m50 fabric and stuffed with 3.5 oz of 900 fill power down. The jacket weighs 6.5 oz in total. I used it over the past 3 days over the AT in NC/TN and I can say it is much much warmer than my old Montbell down inner ever was.

Here is a picture of original jacket when it was primaloft.

For comparison, here is a picture of my first M50 down jacket that is stuffed with 2.25 oz of down and weighs 5.1 oz. This jacket I would say is only marginally warmer than a Montbell down inner.

First down pullover

What surprised me the most was that it was possible to open up the side seams of a kinsman and with careful planning it could be stuffed with down and then sewn back up.

Nice work Jamie. How long did the whole process take? Seems like would take a while for something so tedious. Definitely paid off though.

Ryan, Thanks for the reply. I'm fairly slow with my projects. So yes this one took awhile. I bet 10-12 hours in total. First I had to remove all the stitching on the seams that run under the arms and along the sides. This is a French seam so it is double stitched. After that I pulled the primaloft out. It took a fair amount of time pulling it off any place it was actually stitched to fabric. Next was laying out the baffles. I used chalk to draw them onto the shell. Then I stuffed the collar and jacket top front. Next I sewed baffles and stuffed the remaining body. The same was then done to the sleeves. After that I re-sewed the side French seams, but had to do so without the trimming step as I did not want to loose any width.

So yeah it was probably closer to 12 hours when all was done.

Jamie, that jacket looks great. As others have said, the ratio of fill weight to total weight is very impressive. Nice work.

Thanks for the compliments. They motivated me to finally finish instructions for how to make a down pullover. Here is a link to the instructions on my website.\my_gear\LytW8 M50 Down Pullover Instructions

Any one wanting to do this I highly recommend completing a synthetic kinsman first from You will learn a lot that will transfer into making a down version.
