The ONETWOFIT adjustable weighted vest loads high-density silicone weight blocks rather than the iron or sand pouches most vests use. Silicone stays soft and flexible against the body, which removes the hard-edge pressure points and the rust problem that comes with iron plates. Adjustable range runs 2 to 45 pounds depending on the version, with even front-and-back distribution and a bare vest weight of about 2.2 pounds. The neoprene shell has 0.2 inch foam padding, a zipper closure so it goes on like a jacket, and detachable reflective strips for low-light walks. It is machine washable, which iron-sand vests generally are not. Best fit: rucking, weighted walks, and bodyweight training where you will be wearing it for an hour at a time.
Pros
- Silicone weight blocks stay soft against the body instead of pressing hard edges into your ribs
- Machine washable, which most iron-sand vests are not
- Zipper closure and even front-to-back loading make it wearable for long walks rather than short sets
Cons
- Around $100 puts it well above basic sand vests, and the top weight still tops out below what a serious lifter would want
Frequently asked questions
How much weight can it hold?
Adjustable from 2 pounds up to 45 pounds depending on the version you choose. The empty vest weighs about 2.2 pounds.
Can it be washed?
Yes. Remove the weight blocks first, then machine wash the vest. This is the main advantage over iron-sand vests, which usually cannot be washed.
Will it bounce while running?
Weight is distributed evenly front and back and the zipper closure pulls it snug, which limits bounce. Very fast running still moves any vest somewhat.
Is it comfortable enough to wear under a jacket?
The neoprene shell is thin with 0.2 inch foam padding, so it fits under a coat for walking, though it adds noticeable bulk.
