Top of quality, There are dozens of alternatives available in the market but they alll have the same buckle and mostly same components and the buckles tend to be hard to press and break off. SF has smooth operation buckle. Dia is perfect, Doesn’t give pain like others used to. Pricey but definitely worth it
Excellent quality gymnasticrings. Diameter is perfect for gripping.
Great product but can be better if the straps come with markings.
One of the best equipment I have ever purchase quality and service was awesome
