The most common review of this vest is some variation on "I wish I'd gotten the heavier version." Translation: people grow out of their starting weight faster than they expect. The adjustable design solves that by giving you headroom inside the same vest you started with.
Add one bag every two weeks. Drop one back out if a session feels too heavy. Three size options determine the base vest — pick the 11–20 lb if you're an average adult, the 4–10 lb if you're a beginner or teen, the 20–32 lb if you already know you want serious work capacity.

The adjustable Zelus weighted vest is designed for slow, deliberate progression. Here's how to use it well.
One bag front, one bag back. Let your body learn how the vest moves before you load it up.
Alternate sides so the vest stays balanced. Stop when a session feels uncomfortable rather than challenging.
Most wearers stop at 6–8 bags. Decide whether the next bag is genuinely needed or if your weight is already right.
