EZ-VEST MAX V2 – World’s Heaviest Plate Loaded Weighted Vest (300 lb Capacity) – Adjustable Weight Vest for Calisthenics, Pushups, Pullups & Running – Aircraft Grade Aluminum & PU Leather Padding

This is cool. Right now, I have 12 kg on the font and same on the back. So 53 lb ish. I don't know whether it can hold 300 lb, but its comfortable, and I can add weight as I need to. I like it.

I’ve used this vest for one day so far, transitioning from a 46-pound weighted vest. I’m excited to continue building strength with it. The vest itself is very light (about 6.5 lbs) and does not include additional weights—you’ll need to use gym weight plates or provide your own. The company claims it can hold up to 300 pounds, and it feels quite sturdy with 70 pounds loaded (two 35-lb plates, front and back). It’s both durable and stylish. A few considerations: adding or removing weights *absolutely* requires assistance for me, as I lack upper body strength compared to most other men. (I can’t even lift the vest over my head while wearing 70 pounds of added weight.) Also, while it’s advertised to support 300 pounds, achieving that requires purchasing separate pair of 15 cm extension sleeves ($47 before shipping and tax), as the vest only comes with 9.5 cm sleeves; those longer sleeves can be purchased on the company’s website. Overall, I would say that I’m going to keep both my 46-pound vest and this one. That way, I can wear the 46-pounds vest at times when the gym is closed, and then wear this heavier-capacity vest when the gym is open and help is around.
