Works as advertised for increasing sweat during a workout, but the sizing is inconsistent enough that ordering larger than your normal size is worth planning for.

Overview
A men's zip-front vest built from polymer and spandex to trap heat and boost sweat output during workouts, with a compression fit and anti-slip silicone lining to keep it in place.
This sits in the sauna-suit category rather than a true compression base layer, so the point is heat retention during exercise rather than muscle support.
- Zip-front compression vest with heat-trapping design
- Polymer and spandex construction
- Anti-slip silicone lining
- Machine washable, quick drying
Who it's for
Suited to people who already run a regular gym or cardio routine and want to add a sweat-inducing layer to it. Not a fit for anyone near the top of the size chart, since larger sizes reportedly run especially tight.
Pros and cons
- Compression fit stays in place during activity
- Machine washable and quick drying
- Sizing runs small and inconsistently across the range
- Zipper has failed and detached after repeated use for at least one buyer
- Uncomfortably tight if ordered true to normal size
Performance notes
The recurring complaint is a mismatch between the size chart and actual fit: several buyers needed to go up one to two sizes to get a wearable, let alone zippable, fit, and one reported the largest listed size still wouldn't close over their frame.
