Top-level technical insulation with maximum thermal value, minimal weight - and a helping of warm fuzzy. The R3® Hi-Loft Hoody is our warmest layering piece. Compressible and resilient, it's 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® Thermal Pro® polyester fabric, the plush R3 wicks moisture, dries quickly and caches heat when temperatures plunge. Polartec Power Stretch® panels under the arms and down the sides allow for a clean fit, full mobility and enhanced durability. Soft microfleece lines the collar, cuffs and hem; two handwarmers keep stash secure; a drawcord hem traps heat.
