Our verdict
A plain black long-sleeve compression top in 83% polyester and 17% spandex, sold in sizes up to 3XL. It suits beginners' MMA and no-gi classes.
RDX confirms an 83% polyester, 17% spandex compression fabric with "tightly interlocked flat seams", sold in sizes S to 3XL. RDX markets it across MMA, BJJ and other training rather than as a grappling-specific design. The product page does not mention any waistband grip or anti-ride-up feature.
It comes only in black. RDX's other claims, such as quick drying, are the manufacturer's and were not independently tested.
Beginners who want an inexpensive long-sleeve rash guard for MMA and no-gi classes, including larger sizes up to 3XL.
You want a waistband grip to stop the top riding up (see the Hayabusa Apex Core).

- Six sizes, S to 3XL
- Sold directly by RDX's UK store
Cons
- No waistband grip or anti-ride-up feature stated
