Our verdict
A 360-degree no-foul protector from Rival that covers the abdomen and groin, padded, Rival says, with D3O© impact-absorbing material.
Rival's UK site says this 360-degree protector uses "D3O© Technology", which it describes as intelligently adapting to the intensity of any hit. It has a lightweight, ergonomic design with a hook-and-loop closure, and Rival gives a waist-measurement size chart from S to XL.
It is a newer model than Rival's older "RNFL10 No-Foul Protector 360", which has no D3O. Rival doesn't describe this one as a men's or a women's design.
Boxers who want a full no-foul protector for the abdomen and groin, padded with D3O©. For male boxers, England Boxing's competition rules (Rule 8.4) make groin protection mandatory in competitive bouts.
You're working to a tighter budget. Or you want a protector marketed for a female fit: Rival doesn't describe this model in gendered terms, so see the Rival Women's RNFL3-W Pro 180 instead.
Pros
- D3O© Intelli-Shock impact-absorbing padding, a named and widely used protective material rather than generic foam
- Sizes S to XL, with an exact waist-measurement chart
- Sold on Rival's own UK storefront
Cons
- Our research found no independent evidence that its D3O padding outperforms the foam other protectors use
- Rival doesn't state what the outer or shell is made of beyond the D3O
Why we rated it this way
Protection (4): Rival pads it with D3O, a named impact-protection material widely used in protective sportswear, which lifts it above the normal level for groin protection.
Comfort (3): Rival describes a "lightweight, ergonomic design" with a hook-and-loop closure: the normal standard for a no-foul protector.
Materials & Construction (Not rated): Rival names the D3O Intelli-Shock impact material but not what the outer or the shell is made of, so the build can't be rated.
Value (3): A premium price for a no-foul protector covering the abdomen and groin, which is what protectors at this price normally offer. Its D3O padding is a different material rather than an extra, and we found no independent evidence that it outperforms the foam other protectors use.
