Here’s a photo of the wind shell that I made last week to go with the alpha direct shirt that I made a couple of weeks ago. The photo shows the alpha direct shirt layered under the wind shell. I’m really pleased with how the wind shell turned out. It weighs 1.95 oz.
I traced the seams of an old, well-fitting raglan-sleeved rain jacket to make the wind shell pattern. Then I added seam allowance to the traced pattern. Most of the seams on the wind shell were joined using a serger. The hemming (collar, cuffs, and bottom edge) and zipper were done with a standard sewing machine. This was my first time installing a zipper and first time creating elastic cuffs. Thank goodness for YouTube!
Using a roller cutter for cutting out the pattern fabric was key, as the material really wants to fray. The serger also made the process of sewing all of the pieces together go quickly.
According to the Ripstop By the Roll data sheet for HyperD 1.0 (uncalendared) the air permeability by test method ASTM D 737 is 45.5 CFM. If it ever gets cool again in North Carolina, I’ll try the shell out.
