It's the dead of winter, but the roads are clear and the sun is shining. Pull on the Pearl Izumi Women's AmFiB Drop Tail Cycling Bib Tight and say goodbye to the all-day shivers. Made from a proprietary blend of warming and weather-resistant fabrics, the AmFib Cycling Bib Tight will keep you dry, comfortable, and toasty on the nastiest of winter days.Pearl Izumi's AmFib Drop Tail Cycling Bib Tight is made from a blend of Pearl's Elite Softshell and Elite Thermal Fleece fabrics. These fabrics were selected in order to ensure a hand-in-hand system of consistent warming insulation, effective moisture transfer, and protection from wind and water. The Thermal Fleece fabric picks up the slack in regards to thermo-regulation and wicking, and the Softshell material has been interspersed in key exposure areas to eliminate element intrusion. The two fabrics coordinate effectively, so much so that Pearl Izumi gives the AmFib tight a thumbs up for weather conditions as low as 15 degrees. In case you're concerned of the tight getting too balmy at the upper end of its 40-degree recommended usage, you can ventilate from a drop tail opening at the top of the waist?although its main intention is for easy nature breaks.Knowing that sub-freezing riding is hard enough, Pearl Izumi wants you to have a comfortable and precise fit. To ensure this, they designed the cut to allow full articulation during cycling. The lower leg also follows a contoured shape that leads to a gasket that allows the tight to be worn over a shoe. Not only does this streamline and secure the fit, the design retains an uninterrupted insulation layer. Additionally, the AmFib uses a breathable, but warming, mesh upper and bib straps.To ensure that you're positioned comfortably in the saddle, Pearl Izumi included its Elite 3D Chamois. Constructed from a breathable four-way stretch fabric, the Elite 3D has been pre-shaped for total anatomic conformity. Pearl Izumi used a targeted approach to pressure relief in the Elite 3D. The strategy utilizes three layers of variable density foam; meaning that the pad is thick where your body needs it and thin where it doesn't. Active carbon yarns have also been added to increase thermo-regulation. All of this work results in the simplicity of what you really need from a chamois?dry, abrasion-free comfort. The Pearl Izumi AmFib Drop Tail Cycling Bib Tight is available in six sizes from X-Small to XX-Large and in the color Black.
