Overview
An adjustable weighted vest built from an iron sand filler with a rubber and spandex shell, sized for an 11 to 20 pound range, in black.
The model name states its range directly, 11 to 20 lbs adjustable, which puts it in the light to moderate loading category rather than heavy vests built past 40 pounds. Iron sand filler is a common, low cost way to add adjustable weight, though the listing doesn't state sand pack increments.
- 11-20 lb adjustable weight range
- Iron sand fill with rubber and spandex shell
- Item weight around 10 lbs per listing
- Black colorway
Who it's for
Fits people adding light resistance to walking, bodyweight circuits or cardio who don't need heavy load. Not suited to lifters wanting a vest that scales past 20 pounds.
Pros and cons
- Adjustable within an 11-20 lb range
- Spandex panels aim for a closer, less bouncy fit
- Lighter range suits cardio and bodyweight work over heavy lifting
- Caps out at 20 lbs, no room to grow into heavier loading
Performance notes
Weight comes from iron sand packs inside the vest shell, which is how the 11-20 lb range gets adjusted, though the listing doesn't state how many increments or pack sizes are included. The spandex and rubber shell is what keeps the vest against the body during movement.
