Rab Infinity Microlight Down Jacket The Rab Infinity Microlight Down Jacket is the most protective version of the iconic Microlight and uses lightweight and breathable GORE-TEX INFINIUM™ WINDSTOPPER and is filled with 700FP P.U.R.E recycled down, an ally for all adventure. The Infinity Microlight Down jacket from Rab stays true to its original purpose, an insulated jacket for year-round mountain use, but with the added wind and weather resistance of GORE-TEX INFINIUM™ WINDSTOPPERÂ. This outer fabric is super lightweight with impressive weather protection, coping with light snow, spin drift and moisture. It is exceptionally breathable and soft to the touch, offering a quiet and comfortable hooded down jacket for all mountain activities. Built with zoned micro and nano baffles, the 700FP P.U.R.E recycled down has been body mapped to optimise warmth and breathability where you need it. Suitable for hiking, scrambling, and climbing adventures, it has a slim, active fit and a warm, helmet compatible, down filled hood with a stiffened peak for complete protection. It has elasticated cuffs for a seamless fit with gloves, a full length, durable front zip, a concealed chest pocket and two hand pockets, with YKK zips throughout to safely store your essential items. Highly compressible, the Infinity Microlight can be packed down easily into its small stuff sack and stashed in your pack to be pulled out when the temperature drops.
