Buy the ZELUS for a steady activity at a known load, above all a daily walk. Buy the CAP when the load itself is the training variable and you expect it to change month to month.
Comfort against flexibility
The ZELUS is quieter, slimmer, and more comfortable pound for pound. The CAP can be three different vests across a training year and one ZELUS cannot. Neither advantage is small; they simply belong to different buyers.
Top loads and bulk
The CAP goes far heavier and looks it: a long, blocky vest. The ZELUS tops out at 30 lb in a vest you can wear under a coat. If your heaviest day is a 20 lb walk, the CAP's ceiling is wasted on you.

FAQ
Questions, answered straight
Which is better for a beginner?
A beginner with a fixed routine is happier in the ZELUS. A beginner following a progressive strength program gets more years out of the CAP. The program, not the experience level, decides it.
