Zelus Weighted Vest
Questions, Answered.

Start at 5% of your body weight, then build to 10% as your conditioning improves. For a 150 lb wearer that's 7.5 lb on the low end and 15 lb at the top — the 12 lb flagship is the most-bought size.

Use bust measurement for women, body weight for men. The flagship fits chests 31.5″–47″ — the Z-Fit fits 34″–45.7″. Start at the smaller end of your range so the vest doesn't slide.

Yes — it's a unisex design with adjustable buckle plus elastic side bands. Women with broader chests should size by bust, women with smaller frames typically size down.

Flagship tops out at 30 lb fixed. Z-Fit tops at 15 lb. Adjustable tops at 32 lb with all bags. For heavier loads, pair adjustable with curved vest plates in a tactical carrier.

Wipe the iron-sand flagship with a damp cloth and lay flat to dry. Never submerge or machine wash — water compromises the iron-sand fill. Z-Fit is hand-wash safe.

Cool water and mild detergent by hand. Press water out between two towels, lay flat to dry on a rack for 24 hours. Skip the machine and dryer — heat degrades the SBR layer.

Synthetic materials hold a brief packaging smell. Lay the vest flat in a ventilated room for 1–2 days after unboxing. The smell dissipates within that window.

Lay flat on a shelf or fold loosely in a drawer. Skip the hook — hanging stretches the elastic side bands over months. Air dry fully between sessions.

Yes. The flagship averages 4.6 stars across 15,000+ verified reviews. Iron-sand fill distributes evenly, reflective strips work, buckle stays snug.

A decade of weighted training gear, over 1,000,000 vests sold, ratings averaging 4.6 across the catalog. SGS-certified materials with lab reports on file.

Zelus comes from Greek mythology — a personification of zeal and drive. The brand inherits the connotation. See the about page for more.

Yes. SGS Report CZXHL25001492801 confirms lead and cadmium below detectable limits across every component. EU REACH and US CPSIA compliant.

Loosen all buckles, put on like a jacket, center the weight evenly. Tighten the chest buckle first, then snug the elastic side bands. Take a full breath to confirm.

Walking is the most popular use case. Verified wearers report 10–20 bpm heart rate elevations, 10–15% more calorie burn, and posture improvements over weeks. See the walking page.

Light jogging works in the flagship. For real running, the Z-Fit is the better pick — its body-conforming silhouette stays close to the torso and dramatically reduces bounce.

Lighter loads (≤5% body weight): 30–60 minutes. Heavier loads (5–10%): 15–30 minutes. Cap at 2 hours regardless of load, with rest between sessions.

Yes. The 360° stripes on the flagship are positioned where headlights catch a moving body — front, back and sides. Meaningful safety upgrade for early-morning and after-dark walks.
