Weighted Training Vest 12 Inserts (Empty)

Weighted Vest - Vest 12 - The weight you build yourself

There are times when simple resistance isn't enough. When you need a tool that not only increases intensity but puts you in command of your own form.

The Vest 12 is a vest for those who know that strength doesn't come from comfort. Featuring 12 compartments, a fill capacity of up to 30 kg, and a design with no room for error, this isn't just another piece of exercise equipment—it's a test of character.

It fits like armor. It doesn't wobble. It doesn't get in the way. It's ready for pull-ups, sprints, calisthenics, functional circuits, maximal strength —and everything in between. It's perfect for combat sports, powerlifting, bodybuilding, track and field, climbing, running, and intense aerobics. It strengthens muscles. It accelerates fat burning. It works with you.

Fill the vest with sand, cast steel , iron, or any other available material. The unloaded version gives you freedom. You decide how much you can handle.

Why this particular model?

✅ 12 independent chambers – full flexibility in building the weight – sand, steel, cast iron, gravel – you choose what to fill it with.

✅ Sand filling = approx. 15 kg / Cast steel filling = approx. 30 kg – one structure, two completely different load levels.

✅ Stability under maximum load – wide straps and industrial Velcro lock the vest in place even during intense movement.

✅ Cordura – a material for combat purposes – resistant to tears, moisture, abrasion and extreme conditions of use.

✅ Steel instead of sand – smaller volume with the same weight = more freedom, fewer restrictions.

✅ Tactical comfort – the interior is lined with soft foam to prevent abrasions, even during long sessions.

✅ Visibility without glare – grey, matte reflectors blend in with the design, but do the job in the dark.

✅ Mobility without limits – you can take the vest empty and refill it with local filling in the field.

✅ Tested in practice – designed in cooperation with athletes.

✅ 3-year manufacturer's warranty – proof of trust in the design, not marketing.
