When it's a good thing to have friends, the Black Diamond Neutrino Rackpack is a convenient six-pack of wire carabiners that are anodized to match Camalot colors. The anodized color set makes it super easy for racking and indexing. Designed for the lightweight conscious climber, the Neutrino offers thirty-six grams of wiregate perfection. A compact full-function design ideal for cams and slings, this nimble solution is fast, light, strong, and the right stuff for all-purpose thinkers. The Neutrino also has a larger rope-bearing surface than the Oz, and is lighter than the HotWire while every bit as strong.

Good but bulky
January 22, 2011

These biners are great for racking your cams since you can quickly see which cam you're pulling off your harness, but they're a bit bulkier than other biners. If only Mammut made their moses biner in colors, I would definitely prefer those over the Neutrino. But they're still a quality product, and I continue to use these for racking my #.4 to the #3 C4 camalots.

Love the convenient pack of these multicolored biners! Black Diamond has really come along way and you can't beat Altrec's free shipping on 'em!!

Good biners to rack your pros. Super light and strong, even with gloves.

Excellent Light Weight Biners

They are simple, light weight. The opening is big enough even with gloves. Great for alpine or just cragging.

Hammock hangers
September 25, 2011

I picked up the rack pack to hang my two hammocks. I also used the extras to hang some bits of gear from my harness. I love the colors and they work nicely for relaxing in the trees.

Pros: lightweight, Cons: a bit bulky

Great, lightweight biners.
