### ⭐⭐⭐⭐⭐ Best knee guards
*by D***F on 22 September 2025*

I rode hard and fall hard with these i can still get up and walk away highly recommend

### ⭐ PÉSIMO
*by R***P on 13 January 2023*

PEDÍ TALLA L/G Y LLEGÓ TALLA S/M... PARA COLMO FÍSICAMENTE UNA ES MÁS GRANDE QUE LA OTRA (AÚN CON ETIQUETA DE LA MISMA TALLA). DESAFORTUNADAMENT ME PERCATÉ UNA VEZ QUE HABÍA PASADO EL PERIODO DE DEVOLUCIÓN. PESIMO GASTO INÚTIL

### ⭐⭐⭐⭐⭐ Great fit, excellent adjust strap
*by M***D on 28 February 2021*

My favourite feature, including the great fit, is that there is a quick release on the straps. You adjust them perfectly for you and then use the quick release system so that you never have to adjust them again. Good range of motion and a comfortable fit. I would highly recommend them. They are also quite low profile which is great for wear under pants or in my case, a snowmobile suit. Would work great for motorcycle riding, which is the intended use.
