I really dig the two-way zipper on this jacket, perfect for climbing harnesses! I can't speak to the durability of this jacket, but it seems to be holding up ok so far -- lost a few feathers (within the first two weeks!), but that seems to be the norm with puffer jackets. A few minor gripes: no way to cinch the bottom, a little awkward to pack into the pocket (but very packable/compressible!), and the collar is a little short... still, I'd probably recommend this jacket for the warmth and two-way zipper!
