Great upgrade from the Neutrino

  • Familiarity:I've put it through the wringer

Picked up a pack because they were on sale and really like them. It is always great to have your gear color coded when you are pumped out on a hard move and trying to get something in the wall. The hood is my favorite feature as they don't get snagged unlike the standard Neutrios. They are a little lighter and smaller than the Hoodwire (see oup6090890 comment that compares in good detail) which is great for someone counting every ounce, but I would rather have the slightly larger gate opening for clipping. These are very minute differences here and I couldn't probably tell the difference if you switched them on me, but on paper I like the Hoodwire a bit more. Not to say these aren't great and I use the heck out of them. If you are looking into getting a rackpack, spend a little more and grab the Hoodwires or the Oz. The lack of snags in your life well make up for the price!


Best balance in a carabiner

  • Familiarity:I've put it through the wringer

I've tried tons of different kinds of carabiners, and this has been the best one I've found so far. It's not the lightest carabiner - CAMP and Grivel have lighter. It's not the easiest to clip - a full size bent gate or wire gate is easier. What this does well is balance between the two. Until people actually find adamantium, and start making carabiners out of them, I think it will be hard to find a 'fully functional' carabiner that weighs less.

I use these for racking cams, as well as the Oz quickdraws for sport/ice.


Oz vs. Hoodwire

  • Familiarity:I've used it once or twice and have initial impressions

Very similar to the standard Hoodwire carabiners but lighter and just a little smaller.
The main difference is that they are thinner, meaning a drop from 24/8/8 kN to 20/7/7 kN. Still, if you're using these with cams (SLCD), keep in mind that standard size cams max at 14 kN, and most cams are 10 kN or less.
Note that the biners curve very thin along the top between the gate and the spine, hourglass style, so I wouldn't use these for a garda hitch.

In photo Oz is on left, Hoodwire is on right.

Love 'em

  • Familiarity:I've put it through the wringer

I wanted some lightweight apline draws that I could make for my trad rack. However I never liked the feeling of the hook part when trying to un-load the rope. The rope seemed to always snag.

Anyway I decided to mix and match. My alpine draws now consist of Neutrino's on one end and Oz's on the other (the rope side = Oz's). Color coded and same feel on both ends.


Used these after climbing on a buddies

  • Familiarity:I've put it through the wringer

after pulling down some harder pitches and realizing the benefit of matched color biners / cams I picked these up for myself. I dropped some weight as well.


A perfect BD C3/X4/C4 match

  • Familiarity:I've put it through the wringer

A perfect BD and DMM Dragon cams racking binner. The perfect color match, lightweight, no bulk, easy to operate, no snagging, feels bomber.

The only issue is a lack of orange color which means not so perfect match with Metolius cams.


Great Biners

    These are just great, they just go very well with your cams and can take off some grams. extremely light


    Hooded nose width ~= 11.7mm

      FYI the nose width is ~11.7mm - same as HoodWire (according to Eric @ BD). Internal length (long axis) is also the same - ~95.25mm.


      finally, my gear matches

      • Gender:Male
      • Familiarity:I've put it through the wringer

      as anyone can tell you, the better your gear matches, the harder you climb. in all seriousness though, when you're pumped and looking to place a piece quickly, it's nice to look down to your harness and be able to grab a carabiner by color and know exactly what size cam is going to be attached.

      the size of these is superb. they're very lightweight but not so small that i have a hard time manipulating the rope with them.

      superb companions to any rack.
