In reply to jwa: so you want it to pack down small and be durable..
Thats a hard one to do
People rave about Montane Minimus and Rab Volt jackets, but i wouldnt want to arm jam in them, but the face fabric looks good for general use, I would happily use one for emegency multi pitch caught in rain type jacket
Tougher then you go eVent or gore or neoshell etc, which means spending more and you could still tear it
