What I love most about garbage rings is their flexibility—I can train anywhere. At home, in the mountains, or even in Ibiza at sunrise.

Filip Šebo - Ironman, Ex-football pro

I have these great, world's-first recycled gymnastic rings for workouts not only in the gym, but also with me in the car, so I can exercise anywhere 🤙🏻

Maroš Molnar - 1st Forbes Slovakia Influencer ‘23,’22,’21

I love them. You can feel a good quality of rings, which will give you more control and strength during the workout. The straps set up is the easiest I've seen till now.

Nina Strojnik - Strength and Flexibility Coach

We use them a lot! I don’t have any recommendations. They are the best rings I’ve used. 😀👊🙏

Al Kavadlo - Fitness Coach

Truly the best rings I have used, and I have used all of them. The handcrafted quality is apparent the second you touch these rings.

Marmati is very open about their manufacturing and about the supply chain. Very transparent brand.
