Well done

For 26 years I’ve been searching for the best shorts for everyday use. These are it. Easy to clean, easy to put on, long lasting, look great and most of all feel comfortable. Well done guys these are deadly.

Nice relaxed gym short, finally not too long!

Great relaxed fit and short enough to see you legs working it....I find the others too long for the gym
