Our verdict
The premium, technically-distinguished option in this launch category - a genuine D3O© impact-material claim at a significantly higher price than the rest of the category.
Rival's own UK site confirms this 360-degree protector uses "D3O© Technology", described as intelligently adapting to the intensity of any hit, in a lightweight, ergonomic design with a hook-and-loop closure and a confirmed S-XL waist-measurement sizing chart. This is a distinct, newer SKU from Rival's older non-D3O "RNFL10 No-Foul Protector 360" - the two should not be conflated. No sex-specific design claim is made for this model either way.
Competitive male boxers - for whom England Boxing's competition rules (Rule 8.4) make groin protection mandatory in competitive bouts - and any boxer wanting the most technically distinguished, confirmed impact-protection material in this launch category, via the named D3O© technology.
Buyers working to a tighter budget - this is by far the most expensive product in this launch category. Buyers wanting a product specifically marketed for a female fit - Rival's own copy does not describe this model in gendered terms; see the Women's RNFL3-W Pro 180 in this launch category instead.
Pros
- Confirmed D3O© Intelli-Shock impact-absorbing material - a named, widely-used protective material, not just generic foam padding
- Confirmed S-XL sizing with an exact waist-measurement chart
- Own UK storefront with live GBP pricing and stock
Cons
- By far the most expensive product in this launch category, without independent review evidence to justify the premium
- No sex-specific design claim is made for this model either way
- Exact fabric/shell composition beyond the D3O claim is not stated
Why we rated it this way
Protection (4): D3O© is a real, named, widely-used impact-protection material in protective sportswear - a genuine confirmed distinguishing feature, rated above the category baseline on that specific basis. Comfort (3): "lightweight, ergonomic design" is claimed but with no further corroborated detail beyond that. Durability (3): no independent durability testing was found. Value (2): nearly seven times the price of the RDX cup and roughly double the RNFL3-W in this same launch category, without independent review evidence to corroborate that premium - a genuinely weaker value case despite the confirmed D3O material.

- Manufacturer — Rival's own UK site - D3O construction claim, closure, sizing chart, and price. Distinct from the older non-D3O RNFL10 No-Foul Protector 360 SKU - not to be conflated.
