When the mercury plummets, Rab's Microlight Alpine Down Jacket comes into its own. The jacket features 700 Fill Power down, arranged in a combination of micro and nano baffles to increase core warmth and reduce bulk. The Microlight is designed to insulate beneath a hard shell in extreme environments but can be worn as an everyday jacket too. Its recycled Pertex Quantum fabric features a DWR coating in case of light showers. In cold weather, its down-filled hood with stiffened peak can be adjusted for extra warmth and comfort. The down used in the Microlight is treated with Nikwax hydrophobic formula. Whereas untreated down loses its ability to insulate in damp conditions, hydrophobic down repels moisture and retains its ability to loft and insulate. Your gear dries fast and stays warm. Pertex Quantum ripstop nylon fabrics are soft and packable Zoned lightweight micro and nano baffle stitch-through construction Adjustable hood with stiffened peak YKK zipped hand pockets and large zipped chest pocket Internally elasticated cuffs and drawcord adjustable hem Main Fabric: Recycled 30D nylon Pertex Quantum, 50g/m², with DWR Lining: Recycled 20D nylon, 38g/m² Insulation: Recycled 700 fill-power down Nikwax hydrophobic (water-resistant) finish (153g Size L) Composition: 100% recycled polyamide outer with 100% recycled polyamide lining Fit: Regular Centre back length (Size L): 76cm/30inch Weight (Size L): 466.5g/16.5oz _
