Problems with commercial insulated jackets:

Comments about design:

Weighs 470g, assuming shell 3.3 oz/sqyd supplex from SeattleFabrics.com, lining 1.0 oz/sqyd calendared HyperD diamond ripstop nylon from RipstopByTheRoll.com, insulation 2.5 oz/sqyd Climashield continuous fiber polyester from RipstopByTheRoll.com.

Pattern:

Similar to that of shirt, except remove about 1" from front width to accomodate zipper, different neck opening, different collar, shorter torso. TBC 2016 jacket used neck pattern from shirt versus larger neck opening in back piece of current paper jacket pattern, so probably need to make collar wider in back; also trim inch of top inside front of pattern, since jacket too wide there
