Our ONE short sleeve jersey performs amazing in hot weather with snug aero fit. The main fabric MITI ASTERIA is lightweight breathable 4-way stretch. Soft touch and high wicking properties for a high speed sensation. Helping with breathability is the full zip, so if you do end up getting too hot despite its breathability you can just unzip and let in more air.
A lay-flat neck design, and an Italian silicone gripper lined waistband take care of the extremities. Three pockets for carrying food and spares, and these are well supported so they don't sag even when loaded to the gunnels.
