"Perfect boxers for a busy life that makes for an easy transition between biking around, hitting the gym, and grinding it out at work. Great temperature regulation and love the wind blocking of the pouch for cold weather sports."

    Men’s boxer brief

    Great fabric, great fit. My husband was surprised to find they do not have the slit in the front, but 5 stars anyway.
