    I forgot I was even wearing them

    “Honestly, the first pair that didn’t ride up halfway through my day. I ordered 5 more the same week.”

    No more adjusting in meetings

    Best decision I’ve made for my comfort 
in years

    This isn’t just comfort. It’s confidence, focus, and feeling like yourself again.

    • Before

      Shifting in meetings. Distracted during workouts. Always a little off.

    • Wearing KRYX boxer

      Breathable. Supportive. Feels invisible - in the best way.

    • After

      You’re focused. You’re present. You’re actually comfortable - all day long.

        Bought these for my husband. He wanted to try bamboo underwear. He has found them extremely comfortable. They wash well on a 30 degree wash and seem to become softer with each wash. They are quality underwear that is sold at a reasonable price.

        I’m a big guy and these fit great. No riding up they stay put. Feel great and no chaffing even on heavy work days. This is my second set. First set looks and wears the same even after six months. Replacing all my old boxers with KRYX boxers. customer for life!

        The breathability of these shorts is simply exceptional. No matter what activity I'm doing, I always feel comfortable and fresh.

        The softness of the material is incredible and I no longer feel any of the unpleasant rubbing I had with my previous underwear. 10/10

        Still Not Sure? Let’s Clear That Up.

        Will these ride up during the day?

        Absolutely not. Our no-ride-up design stays in place whether you’re sitting, walking, working out, or on the golf course.

        Is the waistband tight or digging in?

        Nope. It’s firm enough to stay put, but soft enough to never leave a mark. No rolling, pinching, or red lines.

        Are they hot or sweaty in summer?

        Not even close. Bamboo fabric is naturally breathable and moisture-wicking. These stay cool and dry all day.

        Do they shrink or stretch out in the wash?

        No saggy waistband, no tight squeeze after washing. Silkenfits hold their shape - wash after wash.

        What if I try them and don’t like them?

        You’re covered. Try them for 45 days - if you’re not blown away, we’ll refund you. No hassle.
