Description
Best for: Boxing and outdoor conditioning. An outer layer with a hood and a zip pocket.
The zip is what makes this one practical. GRYNDWEAR's sauna jacket is a sleeveless sweat jacket and sauna hoodie with a full-length zip, so you can vent it mid-session, layer it over a training shirt and get out of it without peeling a tight sauna suit over your head after a hard set.
The shell uses a polymer sweat-trapping layer that retains warmth around the torso and raises sweat output through a workout, while the sleeveless cut keeps the shoulders free for pressing, rowing and boxing work. A zip pocket holds a phone or keys, and the hood adds warmth for outdoor conditioning and warm-ups. Flatlock seams and a smooth inner face keep it comfortable over a longer session.
Treat this sweat suit layer as a warmth and sweat aid rather than a fat-loss device: the weight lost during a session is water and comes straight back with your next drink. Hydrate properly, avoid using it in already hot or humid conditions, and stop if you feel dizzy or overheated. If you have cardiovascular issues, heat sensitivity or are pregnant, speak to a doctor before training in heat-trapping clothing. Check the size chart above before ordering. Worn sensibly, it is a comfortable warmth layer for cold mornings and a practical extra for conditioning work indoors.

The Zip Changes Everything
The zip is what makes this one practical. You can vent it mid session when you have had enough heat, layer it over a training shirt, and get out of it afterwards without peeling a tight vest over your head.
A small thing, but it decides whether the jacket actually gets used.
Zip it to the chin for the warm up, open it once the working sets start.
Why GRYNDWEAR

Frequently Asked Questions
Why choose the zip version?

Does it have pockets?
Yes, a zip pocket sized for a phone or a set of keys.
How should I size it?
