I-Beam construction brings each Phantom carabiner's weight down to just 28 grams. Low weight doesn't mean no frills: the Phantom has a reduced gate notch to combat snagging, and more metal in contact areas for reduced wear on equipment.  

• These carabiners are suitable for alpine climbing, trad onsighting, and any other scenario where minimum weight is desirable.
  
• Carabiners with wire gates need a gate notch to achieve their full strength rating. The notches on these carabiners are as small as possible while remaining functional, reducing the chance of them snagging on other equipment.
• Wire gates are the lightest gate type available, and are appropriate for trad, alpine and winter climbing, where minimal weight is desirable. They are less likely to freeze and clog with ice than solid gate biners, making them ideal for winter and alpine climbing.
• I-Beam construction techniques allow carabiners to be lighter without compromising strength. This is achieved through hot forging, a process which allows metal to be made into complex shapes that improve functionality.
• Coloured carabiners allow colour coding of gear on your rack, helping you select the right piece of protection first time on a big trad lead.
