I've owned a couple of Rab eVent jackets over the past few years, including a Latok Alpine, and they've been brilliant. These jackets are breathable, light, easy to care for, and pack down small. The hood fits great, moves with your head, and comes with a wire reinforced brim. The sleeves are pretty long, and the cut of the jacket won't allow it to ride up when you lift your arms.
If you take care of eVent like you should, it'll last ages and stay very breathable. The only way this jacket could be improved is to add some small underarm vents. I think all hard shell jackets should have pit zips, but that may just be me, since I'm on a mountain bike so much. Anyway, it's good kit. If you need a breathable waterproof, you really can't go wrong with a Latok Alpine.
