For conditions so cold your breath freezes before it leaves your lips, the R3#174; Hoody is Patagonia's warmest layering piece. Compressible and resilient, this Regulator#174; fleece hoody is perfect as a toasty midlayer or on its own in chilly, dry weather. A 3-panel, close-fitting hood cranks the thermostat up another notch. Made of high-loft Polartec#174; Thermal Pro#174; polyester fabric, the plush R3 fleece wicks moisture, dries quickly and caches heat when temperatures plunge. Polartec Power Dry#174; panels now run along the underside of the arms and down the sides, allowing full mobility, enhanced durability and contributing to the improved, technical fit.
