The Sedici Close Long Johns was designed to help keep riders comfortable on long rides. The Second Skin Close Weave works to keep compression on the muscles which increases blood flow and thereby reducing muscle fatigue. This means you can ride longer and stay comfortable. The material is designed to wick away perspiration and heat to help keep the body from overheating and keep you dry. The flat stitch panels means there are no annoying seams rubbing against your body so no matter how long you wear the Sedici Close Long Johns you’ll be comfortable and ready for whatever the road throws at you.
