The Aero has a solid gate and a snag-free, clean-nose design; this gives the biner both toughness and excellent handling qualities. You can use it for all aspects of climbing, but it does perform very well at the bolt clipping end of a quickdraw.
New for 2013: DMM have improved the grip and ergonomics of the biner with the addition of an updated straight gate to help with full stretch clips.
