Customer Reviews for Knox Defender Shorts MKIII - Black

Knox Defender Shorts MKIII - Black
July 7, 2020

Very comfortable

My orden no 200519161143 2 pairs of Knox Defender Shorts. I bought these for cycling after my wife came off our tandem and fractured her femur. So I bought two; one each. I ended up wearing the XL size as the fit around the thigh with the L size was too tight for me. My wife found the L size best for her having slimmer legs. I had my first ride out on my own on my MTB in 30 degrees of heat last Sunday. I wore liner pants with a gel saddle pad under the Knox shorts. After a two hour mountain ride I found them amazingly comfortable. I was amazed that these weren't too hot. I felt very confident with the added protection. When it came to Washington them I found that the insert pads were awkward to remove and replace. So I would recommend leaving the pads in place whilst machine washing. So, excellent product, excellent service, thanks guys!!

Seem pretty Good

I haven't worn them yet, I bought them to go under my m/cycle jeans, the weather has dictated that I'm still in goretex though! They seem well made and pretty unobtrusive, I feel that they will give a bit more abrasion protection than material of the jeans alone, also pretty good for the MTB!

So far so good

Worn them once so far. My initial view was they felt a bit odd but the forgot I was wearing them. They fit snugly under my textile & leather trousers. So far so good.

Not yet used in anger

I bought these for trail riding after a recent off convinced me to invest. I'm sure they would have prevented me from getting the mother of all bruises had I bought them earlier!

Not much, not special

Feels a bit uncomfortable to the groin area and also I don't think it's something much from the safety perspective, average.
