OK, so I'm (almost) convinced that I need to carry BOTH a rain and wind shell instead of one heavy rainjacket. Which would you choose?
I've been looking at the following options:
1. Rain jacket
Marmot Essence

How important are pit zips for rainjackets? I noticed the UL ones lack pit zips.
2. Wind shell
Marmot Ion

Montbell Ultralight Wind Jacket

How breathable are these shells? Is breathability inversely related to wind resistance?
Let me know if I should consider any other options.
thanks,
David
