A classic wool jersey is about 290 grams, an early ‘90s synthetic jersey is 170 grams. Our new zipperless mesh jersey weighs about 75 grams almost 100 grams less than a conventional polyester jersey. That’s the difference in weight between a 105 and a dura ace Shimano cassette (which costs over 200 dollars more).
The other big advantage of the zipperless jersey is that all the bunching fabric and stomach bulges are eliminated. The result is a very clean, streamlined fit - even in a cycling position. So it's less rumpled and more aero.
I took up Chinese blossom painting during the quarantine, inspired by the spring blossoms and some free time. Originally the intent wasn't to make a new jersey. I had a few scattered on the floor one night before I tried to paint the branches to connect them. and decided it wasn't a good Chinese blossom painting but may make a nice summer jersey.
