The Mountain Hardwear Men’s Kor Strata Hooded Jacket is an insulated jacket for heading out on the mountain trails. PrimaLoft Gold Active insulation is incredibly light, with plenty of warmth, stretch and breathability. This allows you to stuff it in your hiking pack when the days are warm and the low bulk won’t be too much when worn. The combination of your active adventures and the stretch insulation keeps you moving through the colder temps. Wear it alone or under a shell for plenty of heat.
