The DMM Aether Carabiner keeps rack weight down without giving up security. Hot-forged I-Beam construction holds a 21kN major axis rating in a body that weighs about an ounce, so the Aether earns a spot on both a trad rack and a fast alpine kit. What Our Gearhead(R) Experts Are Saying:"My wire gates have frozen shut on cold mountain mornings, but not on the Aether. I keep it clipped into my alpine rack now, knowing it will still flick open when my fingers are too numb to fight a frozen gate."
