The Signature Jersey is intended to offer excellent support during your warm weather riding, whether it’s for five hours at a stretch, or a simple roll to the coffee shop. This is an updated version compared to the first Signature Jersey Isadore released. They listened to customer feedback and made mini-tweaks to the cut and features in order to increase comfort and add practicality. With this update, they have added hypoallergenic silicone tape on the sleeves for better grip to keep your tan lines sharp.
