The MiR Adjustable Weighted Vest is a 20 lb vest with included iron weights (six 3 lb each) that can be added or removed for customization. The short 11" frame sits high on the torso, designed to avoid low-back strain through front-and-back weight distribution. Straps adjust for fit across sizes, and the vest ships ready to wear.

Weight system: Fixed iron weights in dedicated pockets; adjustable down to 0 lb by removing weights.

Build & durability: MiR backs the vest with a lifetime warranty, signaling confidence in stitching and pocket integrity. User reports are generally positive on durability, though some note the vest runs warm on extended wear.

Fit & comfort: The short profile appeals to runners and HIIT athletes wanting minimal bounce. Front-back weight pockets aim to reduce shoulder/neck strain versus front-only designs.

For whom: Best suited to intermediate fitness enthusiasts, CrossFit/circuit trainers, and rucking beginners in the 15–25 lb range. Less ideal for advanced ruckers or hikers seeking 40+ lb capacity.
