Overview
A men's compression style sauna vest made from polymer and spandex, built to trap heat close to the body during workouts, with an anti slip silicone lining to keep it in place.
The brand recommends sizing up for a closer, tighter fit, since the vest is meant to work best snug against the body rather than loose. Reviewer feedback backs this up directly, with several buyers confirming the vest runs small and needs a size increase from normal clothing size.
- Polymer and spandex construction
- Anti slip silicone lining
- Machine washable, quick drying
- Compression fit for heat retention
Who it's for
Suits people wanting a heat trapping compression vest for gym sessions, walking, or cardio who are comfortable sizing up from their normal shirt size. Reviewers found sizing inconsistent between the XL and XXL options, so it may take some trial and error to land the right fit.
What buyers say
From Amazon customer reviews.
Reviewers consistently confirm the vest runs small and recommend ordering a size up from normal clothing size, with buyers ranging from 5 feet 11 at 250 lbs to 6 feet 2 at 245 lbs reporting a good fit once sized up. Several call out increased sweat output during walks and workouts as the main benefit, along with comfort and no itching compared to other brands. One reviewer found sizing inconsistent, with an XXL fitting too loosely despite measuring to that size, and returned it for an XL instead.
