Phantom Carabiners from DMM are ideal for fast and light alpine ascents or trad onsight success.
The Phantom has been designed with a lightweight wire gate that is crucial in reducing the weight of your rack whilst a small gate notch reduces the chance of snagging on other equipment, without compromising on strength.
The Phantom comes in many different colors, you can either color code your quickdraws for easy identification of different lengths or use them to rack your cams, they come in common cam colorways so even if you don't have DMM cams this practice still applies.
The Phantom carabiners feature I-Beam construction to reduce weight while retaining a strength of 24kN when closed.
DMM is an awesome recreational climbing and mountaineering equipment company from Llanberis North Wales. Founded in 1981 they still make and test all their gear from home.
