One of the best pieces of gear on the planet, these are always on my rack. Aid climbing, free climbing, you can't leave these at home. I think I could climb moonlight buttress with a triple set of these. Get them and be converted!

While it always depends where you climb or the kind of rock you climb, Offsets, originally by Hugh Banner now reproduced by DMM, fit the majority of natural or man-made bottlenecks I come across in JTree, Yosemite, Needles and sandstone.

I have two sets because I find more placements for them than the rest of my rack except for parallel cracks of course.

I was so glad to see these nuts come back on the market in 2008. The aluminum offsets are invaluable on desert sandstone climbs. They are an important part of the rack on most Zion aid walls, making an otherwise sketchy placement bomber. They're also great on free climbs, and often replace stoppers/rocks for me. I'm surprised by how much even the largest size is useful. The anodized color coding is a nice touch too.

The time tested aluminum offset is back, and DMM does a great job. It's amazing how well these things seat into pin scars - they fit so well, it almost takes a bit of fun out of aid pitches because they make it so easy. But I'm not complaining. I've also been throwing them on the rack for free climbing. Basically, anywhere you see a pin scar, these babies will give you a bomber placement.
