- Who it's for
- Trad climbers building or filling out a rack, from beginner to experienced. Notes suggest singles across most sizes, with doubles in the mid-range (0.3–3) for a full, versatile rack.
- What people are saying
- Hosts consistently call these the industry standard and best value in cams. One host notes the camming range is slightly narrower than Wild Country Friends, which can actually complement a mixed rack.
- Worth noting
- One host prefers the Z4 where sizes overlap, but still owns C4s across the full range. Sizes 1–4 are flagged as the sweet spot for weight-to-functionality balance.

Ben Lim, AMGA Certified Rock Guide, Assistant Ski Guide, Apprentice Alpine Guide
These are the standard against which every other piece of traditional climbing protection is measured against. I often even think about stopper sizes in relation to the sizes of C4 cams.

part of my standard rack. I use this for the bigger ranges of cams, I prefer these over the ultra lights as part of my rock kit since they are made with steele cables and last longer. (however, I use the ultra light set ups for the alpine)

A favorite cam in the bigger sizes (1 and up). Can't beat 'em!

Dan Morley, Rock Climbing Guide
C4's are the standard by which all other cams are measured and, in my opinion, the best value for your money. While I do prefer the Z4's for the sizes they're available, I also own C4's in all the sizes and they perform great. My recommendation for building a full rack of cams to tackle nearly any climb: get one of each of sizes 0, 0.1, 0.2, and 4; get two of each in sizes 0.3 to 3.

The long time standard in cams! BD C4s are hard to beat, long lasting, easy to use, and at a reasonable price point. I use C4s in sizes #1 and up, and generally carry two each sizes 1-3, supplementing with larger sizes as needed. For smaller cams I prefer the Z4, and will often use Ultralights when concerned about weight.

The C4 Cams are the classic BD cams that have remained true to their capabilities. This link will allow you to purchase individual cam sizes to fill the void in your rack.

BD cams are the workhorse of my rack. If you're looking to buy cams for the first time, buy a rack of Camalots.

The gold standard in cams. For a beginner rack, a single set of #0.3-#3 is a great range for Colorado.

The tried and true and refined trad classic. Ubiquitous, durable, dependable without being flashy.

These are the bread and butter cams that should be on every trad climbers rack. Sizes 1 (red) through 4 (grey) are the perfect balance of weight and functionality.

Industry-standard cams. I use the classic C4 cams for size #1 and bigger

Tried and true cams. I prefer Z4s for the smaller sizes and have C4s from 1 through 6.
