    Great shorts. So light you hardly know you’re wearing them. Will definitely get another pair (or 2) of these!

    Got myself the pink shorts to compliment my pink coloured rash guard. The shorts fit perfectly for me and feel very robust for no gi. Never feel like they will rip so obviously of very good quality. Thinking of getting more when I can!

    No problem with sizing, doesn’t have any restriction of movement at all!

    The best shorts in the game, lightweight material but still super strong, really nice fit and love the colour ways.
