Your Sunday morning may start off silent and gray, but after you revive yourself with a cup of Earl Grey and toast, you'll be feeling ready to conquer the world wearing your Sunday Best. The kit's design features St. George's flag and the Tudor Rose brought together in Competitive's own modern twist on the iconography of our friends across the pond. Like in our previous collaborations with Castelli, the Sunday Best Jersey is based on the Team Jerseys platform. Its body is the same proprietary Prosecco Strada fabric, which is appropriately English with its staid yet effective blend of gently compressive stretch, breathable weight, and all encompassing comfort. The result is a conforming fit that helps to alleviate the fatiguing effects of road noise. It also breathes well and, courtesy of the material's titular Prosecco treatment, banishes moisture with quiet efficiency similar to an old aristocratic family overlooking royal indiscretions. The material's controlled stretch means that the jersey had to be cut to a form fitting pattern. The seams are shaped to the body while it's in the cycling position, and the sleeves have been shifted forward to match your posture while stretched out on the bars. While this fit may feel tight across the chest when you're off the bike, it accommodates an in saddle reach without bunching or restriction. The jersey is finished with a full length front zipper and the standard complement of three rear pockets.
