Overview
A short-sleeve compression top built from spandex, polyurethane and polyester, with a mostly-polyurethane inner lining meant to trap body heat and increase sweating during a workout. It functions as a snug shapewear layer rather than a standalone garment.
The heat-trapping claim comes down to the polyurethane lining acting as a thermal barrier while you exercise, which increases how much you sweat in a given session, not a mechanism for burning extra fat on its own. It's meant to be worn during an existing workout routine, layered like regular gym wear.
- Spandex, polyurethane and polyester blend
- Polyurethane inner lining for heat retention
- Compression fit through torso and waist
- Short sleeve, gym-ready cut
Who it's for
Fits people who want a snug, heat-retentive layer to wear while training and don't mind extra sweating during a session. Not aimed at anyone with heat sensitivity or expecting the garment by itself to change body composition.
Pros and cons
- Compression fit shapes the torso and waist
- Polyurethane lining raises sweat output during workouts
- Short sleeve cut layers easily under gym clothes
- Heat-trapping design isn't suited to hot climates or heat-sensitive users
- Effect is limited to sweat during exercise, not a workout program by itself
Performance notes
The polyurethane inner lining insulates against heat loss so body warmth builds up during exercise, prompting more sweat than the same workout without it, while the spandex and polyester blend keeps the fit stretchy and compressive around the torso and waist.
