Whats on your harness?

ATC guide on locker.
Metolius Bravo.
Nut tool.
MAYBE a big wiregate with 48" runner.
That's all folks.

spare thong in a baggie....I typically shit myself on trad leads. Of course clipped with a wiregate biner to back loop of harness

(The baggie's then for the soiled one - I think these things out)

Locker wrote:"A couple spare lockers" I've been told MANY times that one is wayyyyyyy more than enough.

Depending on route. My typical rack is 4, double 3, double 2, double 1, double .75, .5, .3, nuts, tricams, 120mm trad anchor with 2 lockers, 9 runners, 5 draws, nut tool, guide style belay. Sometimes prussiks and 10' webbing for cheap bailing. Knife in chalk bag is definite. Usually keep my gear on a shoulder strap and draws, runners, passive and anchor on harness as leader and prussiks, spare webbing, and shoes/water/rain gear as follower.

I like the quote from old mr Black Diamond: "The more you know, the less you need." That holds true for climbing.

So it makes sense for different people to carry different amounts of gear on the same climb. If you know exactly the pro you need, carry just that - if you have no idea and want to climb it without beta, carry what you think you might need, which will probably be more.

I am sure the weight on my harness will decrease as my knowledge increases. For now, on most climbs I carry

Pro
2 prussic loops on lockers
Large locker for munter and
Belay device (if I'll be following)
2 small lockers
2 48" extendable draws
2 24" extendable draws
1 10' loop cordalette
6-8 quickdraws
chalkbag
gerber multitool in zippered pants pocket

I have a short memory, so I'm starting to bring a notebook and pen (i.e. "no good rap station from top of pitch 3") Usually put an extra belay device on partner's harness. I also make sure my partner is familiar with all the gear and how to check and use it.
