The lightweight Rab Men's Boreas Pull On Jacket is an excellent addition to your climbing wardrobe for spring's changeable weather. Its Matrix SWS fabric features four way stretch for unimpeded mobility, and it resists wind, dries quickly, and is highly breathable to keep your hard working body as comfortable as possible on the wall. Rab also added a Polygiene Stay Fresh antimicrobial treatment that reduces odor causing bacteria by 99% to keep the jacket fresh smelling for a long time. A slim fit drastically reduces bulk and weight without inhibiting your movements on the wall. The Boreas also features a 12 zip front for ventilation, a close fitting scuba hood that fits under climbing helmets comfortably, flatlock seams to keep chafing at a minimum, and a zippered chest pocket that secures your valuables.
