Definitely after a waterproof-breathable number, with a focus on breathable (& 'water resistant') rather than waterproof.

Just looked up the Borah - that looks like what I'm after. Just enough to keep wet misty stuff & spray off. I like how it doesn't bother with a waterproof face part as that's the part that is well covered by a tarp. You've found it to breath a-ok? No wet foot area on your sleeping bag? Is yours the argon or M50? I'm assuming its the Silnylon 30D floor rather than the Dyneema/Cuben?

Thanks.
