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.
Strengths and trade-offs
Drawn from this product's published specifications.
- 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
- Compression and heat claims depend heavily on the wearer, not independently verifiable
- No buyer reviews yet to confirm fit or durability over time
Performance notes
The thermal polymer fabric is meant to trap body heat and raise core temperature during activity, while two flexible steel bones in the back and waist panel provide structured compression and support posture. A reinforced zipper plus nylon hook-and-loop fasteners are meant to keep the fit secure through movement.
