The Primaloft Gold Active insulation keeps you warm, without the excess weight or bulk. The stretch and breathability make this an adaptable piece you can wear anywhere.
Mountain Hardwear says:
It's all in the core. That's why the Kor Strata™ Vest brings the warmth of Primaloft® Gold Active insulation into a compact, adaptable package. Sometimes, we don't need full coverage. We're just hardkor like that.
Mountain Hardwear's Kor Strata Vestutilizes the new 'Active' PrimaLoft Gold insulation, with higher breathability and no need for quilting, so no cold spots. The 'Active' insulation provides plenty of warmth without weighing you down or taking up much room in your pack while also featuring a good amount of stretch for greater freedom of movement.
The face fabric is weather-resistant, offering a good amount of protection from light rains and winds. There's a softness to both the inner and outer but the stretchy nylon ripstop outer still feels like it can stand up to a bit of rough wear.
Feature-wise it has everything you need; there's two good size handwarmer pockets and one chest pocket all with zip closures. The arm holes are elasticated and the hem has a pull drawcord for keeping cold drafts out. Overall a warm and highly versatile vest, designed for a cool autumnal day at the crag, yet warm enough for an alpine start.
