HYBRID ALIENS are regarded as the aid climbers best friend due to there amazing ability to plug into thin cracks, pin scars and pockets. You'll find HYBRID ALIENS become a regular part of your free climbing rack as well due to their unique ability to make solid placements in radical flaring cracks. Pairing different size cam lobes together on opposite sides of the flexible cable stem allows HYBRIDS to fit cracks with both pairs of cams engaged at the optimum (mid point) position rather than having to "force fit" a standard cam into a flare. This assures faster and higher strength placements for leader and also easier removal for your partner. Contemplate this - most cracks flare more than you may realize (which is why spring loaded cams work so well in the first place) - if a standard cam works pretty well in moderate flares, then the reciprocal is true - ALIEN HYBRIDS will work equally well in mostly parallel cracks and have the distinct advantage of secure placements in flares. Check 'em out - you'll be amazed at how often you'll prefer placing a HYBRID ALIEN. Be sure to place your ALIENS (and all cams) at 50% closure - for maximum holding strength. Each ALIEN cam holds true to the orginal CCH design (with improvements - like the flexible trigger control cables) and are UIAA certified and CE approved. Made in Spain.
