Softshell, you know i have a 300wt jacket that feels more comphy than any thing ive tried, as long as i put a windbloc vest on under it its great,lots of flexability,i have pockets in the vest for handwarmers to fit in front and back and my core stay's plenty warm and the pit zips regulate it just fine, no rain forest effect at all,if the weather gets real bad, i slip on a hard shell that i always carry on the rack...im pretty satified with the fix! joe
