    Solid pick

    Good value and comfortable for training. Sizing ran a touch snug for me but settled after a wear.

    Really good

    Comfortable and flattering. Took one star off only because I wanted a deeper colour.

    Daily driver

    Wear it to the gym and out. Holds shape, no pilling, dries fast.
