We understand the need for space, especially in the high friction sport of triathlon. Between all of the running, swimming, cycling, and transitions in between, it's hard to imagine that one skintight, race cut top can fit perfectly all day. If you're of the same mindset, the Louis Garneau Pro Semi Relax Sleeveless Top is for you. Slip it on, and enjoy a comfort in tune with silence you won't even know that it's there. To perform in and out of the water, Louis Garneau made its Pro Sleeveless Top from a blend of materials, with each fabric playing a vital role in the tri characteristics of the top. Starting with the primary material, a jack of all trades called Delfino, the fabric features a dimpled mesh structure that efficiently breathes, wicks, and vents during your run or ride. And whether you're in the water or out of it, the fabric has incredible hydro and aerodynamic properties. Delfino also has slight compressive qualities for muscle support, and is resistant to chlorine for training in the pool. However, in the tri arena, the largest benefit to this material is its resistance to water absorption. This means that you'll be drier, faster than the competition when it's time to jump in the saddle. To guarantee a full range of movement, Garneau used the Carbon X Mesh fabric for inserts around the abdomen region. This material is extremely malleable and promotes a better blood flow while supporting your muscles. In fact, Garneau claims that its compressive properties promote a 10 to 20% increase in resistance to fatigue. This translates directly to the retention of your core strength. The Carbon construction also possess immense anti static properties that prevent the body's absorption of random static energy or air born pollutants. The Pro has what Garneau calls its Semi Relax Fit, but we call it ideal for ultra racing. The arm and neck apertures have been designed for comfort, and along these lines, flatlock seams have been used throughout the suit to m...
