Overview
A pullover sauna jacket made from a heat retaining fabric the brand calls Heat REG V3.0, with a waterproof polyester shell over the top. It is built to trap body heat during exercise rather than to insulate against cold.
This is workout apparel meant to increase sweat output during training, not general outerwear, and the windproof, water resistant shell is there to hold heat in rather than keep rain out for long stretches. Sizing runs by model code, and this listing covers a black, size large jacket.
- Heat REG V3.0 heat retaining fabric
- Waterproof, windproof polyester shell
- Anti-odor fabric treatment
- Pullover, size large, black
Who it's for
Suited to people already doing structured workouts who want to increase sweat during that session. Not a substitute for real weight loss methods, and anyone with heat sensitivity or cardiovascular concerns should be cautious with any garment designed to raise body temperature during exercise.
Pros and cons
- Waterproof polyester shell blocks wind and light rain
- Pullover design goes on and off quickly
- Ergonomic cut allows full range of motion for running or boxing
- Fabric is designed to trap heat, a health consideration for some users
Performance notes
The shell is a waterproof polyester layer over the heat retaining inner fabric, built to shed light rain and wind rather than let heat escape. The brand describes an anti-odor treatment on the fabric aimed at reducing the smell that builds up from heavy sweating during use.
