The De Marchi Perfecto Lux Men's Bib Short stands atop the brand's hierarchy as the pinnacle of comfort and impeccable construction. Given De Marchi's excellence in these fields, that puts the Perfecto Lux pretty damn near the top of the list, industry wide. For the fit, De Marchi refines its legendary Contour Fit concept with Contour 2. 0, providing a supportive fit with strategically placed panels that allow virtually unlimited mobility and stretch. Panel shape and lay out is only part of the story, though, as De Marchi's meticulous obsessiveness extends to the composition of each panel. By employing different fabric weights and blends across the front, sides, hips, waist, and inner thighs, De Marchi ensures the Perfecto Lux offers compressive support that it claims increases blood flow to speed recovery, reduces muscle vibration, and improves endurance. The fabrics' weights range from 190 to 240gsm, and the highly elastic Lycra blend ensures that, while compressive, the material still stretches and returns as well as any synthetic blend with a denier high enough to justify its use in bib shorts. The minimalist straps are made of a seamless jacquard elastic that moves as you do without irritating your skin or causing sweat to build up. At the back, a slim microfiber mesh panel allows moisture to easily evaporate, and gel strips at the hems ensure the shorts don't ride up or rub uncomfortably against your skin. De Marchi caps off the Perfecta Lux with its exclusive Elastic Interface CRM EVO chamois. Balancing comfort and sensitivity is a delicate task, and the CRM hits the sweet spot by welding two triple density half moon shaped elements together to support your sit bones while leaving a channel to shield your precious cargo from pressure. In a departure from its usual super clean and simple aesthetic, De Marchi also incorporates large reflective panels along the side of each leg to increase visibility to other road users in low light conditions.
