## Description

Shop Shock Doctor Ultra Pro Carbon Flex Athletic Cup for Sports - Protective Cup for Contact Sports. Free delivery and returns on all eligible orders.

Review: Finally A Cup Large Enough - Even the size L is too small. But luckily I found this cup from shock doctor with a size XL. Unfortunately the size XL cup + supporter combo you buy from shock doctor doesn't use a size XL cup, it's smaller, only the supporter is size XL.
Review: Brilliant for sparring - I use this cup for Muay Thai sparring as I hate the standard fighting groin guards as they are so uncomfortable. Not only is it big enough but it’s really comfortable and taking a shot to the balls hurts the same as if you were wearing a Muay Thai brand guard if not less.

### ⭐⭐⭐⭐⭐ Finally A Cup Large Enough
*by M***L on 10 December 2023*

Even the size L is too small. But luckily I found this cup from shock doctor with a size XL. Unfortunately the size XL cup + supporter combo you buy from shock doctor doesn't use a size XL cup, it's smaller, only the supporter is size XL.

### ⭐⭐⭐⭐⭐ Brilliant for sparring
*by J***A on 25 November 2025*

I use this cup for Muay Thai sparring as I hate the standard fighting groin guards as they are so uncomfortable. Not only is it big enough but it’s really comfortable and taking a shot to the balls hurts the same as if you were wearing a Muay Thai brand guard if not less.

### ⭐⭐⭐⭐⭐ Strong enough to take a hit
*by M***B on 1 July 2018*

This box has already saved me a great Deal! It is comfortable and will take a baseball on a short hop head on (no pun intended). Worth spending the money on as it will give you confidence in its ability to take a hit. Can be snug for some men though as quite narrow at the bottom.
