vajsab: you have to open the zipper vents on the jacket. Open the ones in the arm pits and other various zippers depending on which jacket you have when walking. The jacket will keep you dry but humidity will build inside if you dont let it breathe while your traveling in the woods. once your seated, wait a minute till your body cools down a bit then zip up the venalation zippers. Rivers west knows that happens that why they put them on there clothes.
