I think that vests often get overlooked as a necessary piece to a quality kit. They are so versatile and can be easily stored in a jersey pocket. I find vests to be perfect for rides that may start chilly or ones with climbing and descending. Take the vest off or unzip when you start to put down the watts; put it back on when you start hauling the descent. I love the fit of this vest and that it has 2 large pockets. Machines for Freedom is 100% focused on making cycling a better, more inviting place for ladies. With the rad work they are doing and the amazing products they are putting out, I cannot recommend a brand more.
