The Women’s Corsa Tank Top front and side panels are made mainly from Giordana’s Gi27 fabric. It is a supremely soft material largely due to the special hydraulic treatment process they put it through which smoothes out the knit, creating an almost velvety feel. This makes the material feel so comfortable against the skin that you won’t want to wear a baselayer, which is probably a good thing since you’ll be wearing your sleeveless jersey on the hottest days. Gi27 also has excellent elasticity, which means that it will give you a racing fit without encumbering you. It also has the added advantage of being extremely colorfast, so that you won’t have to worry about fading colors or bleeding dyes in your laundry.
