When it comes to your core, go-to staples, you likely want to equip yourself with solid basics that go with everything. Rapha's Core Long-Sleeve Jersey makes a strong argument for itself, with clean lines, classic styling, and technical construction that holds up to long miles on spring rides. It's crafted from odor-fighting polyester that wraps you with a fleecy, brushed interior hat keeps you snug and warm on cool morning sprints and fall expeditions, all the while wicking away perspiration to help keep you comfortable when your heart rate rises. It's built with a similar cut to Rapha's Short Sleeve Core, but the fabric is just a bit thicker, so you can handle cooler temperatures. Full-length raglan sleeves and side panels are cut for stability, and shaped to fit the body just right when you're in your cycling position. All of the fabric and details are color matched to a T, including the ribbed collar and cuffs, concealed zipper pocket, and laser-cut rear gripper lined with silicone, keeping your aesthetic on point, while your fit stays locked into place.
