Review: great product - these boxer shorts are great, they fit well and do exactly what they say, used them this weekend for trail marathon and had no chaffing and even though was a hot day was comfortable throught, more expensive than other brands but for the comfort they give on longs run they are easily worth it
Review: Very comfortable - Bought these for my husband who is currently training for a marathon. He says they are incredibly comfortable, but they do seem to be wearing quite quickly. Have bought another 2 pairs to rotate and hopefully slow down the wear on each pair. Not 5 stars as these are expensive.

### ⭐⭐⭐⭐ Very comfortable
*by J***D on 11 June 2019*

Bought these for my husband who is currently training for a marathon. He says they are incredibly comfortable, but they do seem to be wearing quite quickly. Have bought another 2 pairs to rotate and hopefully slow down the wear on each pair. Not 5 stars as these are expensive.

### ⭐⭐⭐⭐⭐ Wouldn't run without them!
*by M***. on 11 October 2018*

Fantastic product that completely negates any chaffing. Can't recommend them highly enough, and I certainly wouldn't run without them any more. Even during the long, hot summer I wore these on every training run for a recent half marathon. They are ideal for all weather conditions - hot, cold, dry or wet. Also like the strapline 'Don't run Commando'!
