    Works great for my needs. A little wider gusset would be appreciated to cover all the lady bits.

    Style has changed disappointing

    i purchase the exact same boyshorts a couple years ago and loved them. the style has changed now and the back seam on the gusset is much higher and shows a seam line on tighter pants. i can also feel the seam and it's uncomfortable. i am debating whether or not to keep these items.
