I was looking to order some descending rings and a couple of the CAMP Wire Nano biners but REI was out of the biners.
I found them on sale at Backcountry.com for 4.71 each. They are 6.95 each on REI. Here's the linky:
I was also going to buy some descending rings from them but when I did an Backcountry search it came up with nothing, but they offered me another $10 off because they couldn't find what I was looking for. I hope this link works (if not try searching for descending ring):
This $10 discount covered my UPS ground shipping plus a little extra. I got 4 CAMP Nano biners for ~$17.00 shipped. Great deal.
Basically switching from the biners I currently use on my HH to the CAMP nano will save me about 1.2oz total from the Black Diamond biners I am currently using. Here's the specs on the CAMP:
Major Axis Strength: 22kN
Minor Axis Strength: 10kN
Open Gate Strength: 9kN
Shape: Offset D
Gate Type: Wire
Recommended Use: Trad and alpine climbing
Weight: 1oz (28g)
