If you are looking for a great winter cap with excellent coverage, fit, and fabric technology, the plainly named Louis Garneau Winter Cap makes a serious case for the best option out there. The Winter Cap is by far an essential piece and will be perfect for training cyclists, commuters and weekenders, all of whom must or will ride in cold temps if the conditions are otherwise manageable. It will block wind and water, but isn't designed for the wettest days unless warmth is all you prefer.

Made largely from the 4-way stretch Vertexx fabric, this well-conceived cap is thin enough to fit under your helmet, but warm enough to keep you riding through the winter. Excellently shaped ear flaps that feature reflective trim can either be worn down to cover the ears, or rolled up and tucked in on slightly warmer days. The lightweight material is brushed on the inside surface, giving it just enough loft to insulate but not enough to stifle you during long periods of tempo pedaling. The extended flap is a must-have for windy days, and the brim is just as important when frigid precipitation inevitably starts falling. This is brimmed cap that can easily be stowed in a jersey or shell pocket, or worn from the time you clip-in to the time you finally decide to find indoor warmth.
