Awesome biners to add to any rack. I prefer the bronze color as it stands out against the rest of your gear. Easy to clip, sturdy, strong and reliable. Great as an extra biner for just about any activity when you want to keep it light. Grab a few of these to round out and lighten up your rack for any adventure that involves some technical work- mountaineering, canyoneering, trad, sport..etc.

Small, small, small, light, light, light. These are great little biners and they don't get much more little than this for climbing. The opening is correspondingly small, they would be VERY tough to handle with gloves on and they give up a little in ultimate strength, but if light is right for you these might be the only way to go. One exception: if light AND color-coded is helpful to you, the Black Diamond Neutrino wiregate offers a wider selection of bright colors (which exactly match those of their cams, natch) in return for a very slight weight (and size?) penalty compared to the Camp Nano. Color-coded rack not on your list? The Nano is the lightest of them all.

I really dig these little biners. I use them on my caving chest harness to attach to my chest ascender. So light weight, it doesn't even feel like it's there!

Pick up some of these to have around as extras. Cheap, quality, just a good standard non-locking biner.

I got a bunch of these and paired some with long BD spectra dogbones. I like taking too much gear and sewing it up when I get scared. These lightweight biners make that possible. They are much smaller than a standard biner, so they will probably be harder to handle with gloves in winter.
