If any one item can be said to be the undisputed king of Pearl Izumi's cold weather range, it's the P. R. O. Softshell Jacket. This is because its combination of race ready fit, function, and understated aesthetics also make it the ideal jacket to establish your rule over all manner of winter conditions. Other jackets in Pearl's line, like the P. R. O. Softshell 180, use a mix of Softshell and other fabrics in order to keep you from overheating in cold conditions, but this jacket is meant for capital C Cold conditions, so it offers no quarter to winter. The P. R. O. Softshell uses Pearl's Softshell material throughout its construction, providing a level of wind and water resistant that is only rivaled by the amount of insulation netted by the slightly lofted lining. The fabric provides an accommodating stretch, so your cold weather armor doesn't actually feel like armor, and it doesn't compromise breathability, either, so water vapor will move freely from the inside out, even while the outside water is denied entry. The jacket's construction incorporates a small army of thoughtful details. The full length front zipper has corresponding internal and external draft flaps at the upper portion to keep the wind's probing fingers at bay. Both the small and large rear pockets are zippered to provide a similar courtesy to their contents, and the larger pocket can be accessed on either side of the smaller one. From the collar, which accommodates an in the saddle posture, to the contoured sleeve to the shaped cuffs, the jacket was put together to provide a sleek, race cut fit that eliminates any excess material and flapping, even while you're stretched out on the handlebars. Reflective elements help keep you visible in low light conditions. The Pearl Izumi P. R. O. Softshell Jacket is available in five sizes ranging from Small to XX Large in the colors Black, BlackMykonos, and Blacktrue red.
