Early morning starts or wintertime mountain adventures have nothing on the Rab Modulus Pull-On Jacket. Featuring Thermic Pro fabric, the Modulus Pull-On Jacket is water-resistant, windproof, and temperature-regulating. The slim fit and stretch properties make it easy to layer with, and the set-in sleeve construction gives us better freedom of movement. The finishing touches include thumb loops to keep the sleeves in place and two zippered pockets on the chest and sleeve to stash important items.
