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.
Very cool, <2oz is tough to beat. I been wanting to put together a windshirt for trail riding and this is just another push to get me cutting out pattern pieces.
Did you have any trouble tracing and adding in seam allowance? I have no experience sewing but I have been thinking of tracing a heavy, lined, yoked rain jacket inorder to try to make the same thing out of silpoly.
I added 1/2 seam allowance for all of the “joining” seams and 1 inch seam allowance for hemmed seams.
The tracing was pretty simple. I’m a total novice sewer of clothing, so you can definitely do this. Just be sure to practice stitching on some scrap silpoly first to get your thread tension and stitch length right before you start sewing on your pattern.
