Venum Challenger and Competitor combine a cup with a Dry Tech fabric supporter. The manufacturer describes Challenger as having two layers and Competitor as having three; the layer count alone does not tell you which will fit better.

Rival RNFL10 360 is a larger boxing protector with a wider padded section around the waist and hook-and-loop fastening. Compare coverage and the space needed under your shorts too. It is not a direct substitute for a small cup for every type of movement.

Start with your waist measurement and the chart for the specific model. A Venum M may not match a Rival M. With a cup and fabric supporter, check both the supporter’s fit and the space inside the cup.

When trying it on, squat, raise a knee and take a few side steps. The guard should stay in place without its edges pressing painfully. If the chart is missing, send the model name and your waist measurement to info@bjp-store.cz.

Fit the cup into the supporter intended for that model and follow its instructions. Ordinary compression leggings are not a cup supporter by themselves. If they have a pocket, check its purpose, size and compatibility with the cup.

Try the complete setup with your training clothes. Shorts or leggings should not pull the guard out of position. If it moves even during slow movements without contact, correct the fit or size before sparring.

Not automatically. A larger boxing protector may interfere with kicks, deep squats or transitions to the ground differently from a compact cup. Try the movements you will use in class.

For grappling and BJJ, check the rules on rigid protectors, which can press into a partner. Some competitions do not allow them. Before buying for an event, ask the organiser whether the type is permitted; approval for boxing does not mean approval for another discipline.

The cup and fabric supporter may need different care. If the insert is removable, take it out as instructed before washing the fabric. Check the label for temperature and washing method; the Dry Tech name alone does not establish either.

Do not machine-wash or tumble-dry the padded Rival boxing protector. After use, wipe away sweat and let all parts dry completely away from direct heat. Do not put damp equipment in a closed bag.

Before use, inspect the cup, soft edges, seams and fastening. Cracks, deformation, sharp edges or a stretched supporter are reasons to stop using the damaged part. The same applies if the guard repeatedly slips and cannot be fitted correctly.

Do not glue a damaged cup or reshape it with heat. If replacement parts are available, check compatibility with the exact model; a similar size or the same brand may not be enough.
