The women's CATALYST jacket works as a cold-weather midlayer during physical activity or on its own when things heat up. Polartec HighLoft fabric keeps you dry and retains its shape. Zoned Power Stretch panels at the sides, underarms and cuffs improve the fit and breathability of the hoody. The high collar keeps your neck protected. Flatlock low-bulk seams reduce abrasion. Two zipped pockets allow protected access. Thumb loops and a hem drawcord secure the fit.
