Can I run in a weighted vest?

Reviewers caution that most adjustable iron-plate vests bounce too much for running. Runner's World and r/Rucking commenters specifically recommend snug, low-profile vests with even weight distribution (such as the BAGAIL Comfort-Fit or compact 1000D Oxford designs) for jogging, and they advise capping running load at roughly 5–10% of bodyweight to protect joints.
