Overview
TrainingGirl's sauna suit is a heat-trapping vest and waist trainer in one, built with a thermal polymer fabric, two flexible steel bones and a zip plus hook-and-loop closure for workouts or daily wear.
It combines two garments into one: a sauna-style sweat vest meant to raise core temperature during exercise, and a waist trainer with boning for compression and posture support. The chest panel is designed to keep the bust supported so a sports bra can be worn underneath.
- Heat-trapping thermal polymer fabric
- Two flexible steel bones for support
- Reinforced zipper with hook-and-loop closure
- Chest-supporting panel for sports bra wear
Who it's for
Aimed at women who want a compression waist trainer with an added sweat-inducing layer for workouts like cardio, weight training or yoga. Not a substitute for diet or exercise, and the seller's own speed claims should be read with that in mind.
Pros and cons
- Combines a sweat vest and waist trainer in one garment
- Steel boning adds structured back and waist support
- Reinforced zipper and hook-and-loop fasteners for a secure fit
- Chest panel design allows wearing a sports bra underneath

Performance notes
