Rab designs many garments based on the demands of climbing and ski touring trips. This also applies to the popular and updated Neutrino Pro jacket: the cut and details are equally at home whether you're climbing or belaying a friend, or just hanging around at a cold campsite. Compared to the previous season's model, one inner pocket has now grown in size and serves as the jacket's own, integrated stuff sack. In addition, the down is now impregnated to be water repellent with Grangers Down Defend, not Nikwax as previously. The outer fabric used is Quantum Pro from the legendary manufacturer Pertex. This fabric is extremely strong for its weight and offers excellent wind protection. The jacket weighs 520 grams, and with these materials, that means excellent insulationit is one of the warmest jacket models with sewn-through construction. Despite this, the jacket can still be packed into a relatively small space. - Regular fit - Goose down fill: European goose down, Grangers-treate
