I have tested a bunch of waterproof fabrics including gortex, paclite, hyvent, pertex...tried on a bunch of jackets from makers arcteryx, patagonia, marmot, tnf...and think that this jacket stands out for 3 reasons: 1. eVent - it really does vent better. 2. light weight/durability - around 10oz with reinforced elbows. 3. great hood design - this thing really synches down to keep the elements out.
