Run another lap on your favorite climb in the brisk autumn weather in the Mountain Hardwear Kor Strata Hooded Jacket. Featuring a lightweight construction using top-of-the-line Primaloft Gold insulation, this jacket keeps you warm but ventilates out excess heat. That way you're not getting overheated while working that crux pitch of a climb that's still in the shade in the morning. The underarm gusset and mechanical stretch nylon fabric allow for a comfortable range of motion that won't restrict you as you reach far above your head looking for a hold to pull on. The adjustable hood can easily be pulled over a helmet if the weather turns and your head needs a little extra protection.
