    A classic!

    Finally added this classic design to my Knobby collection. As always, incredibly comfortable and well made. I really love this older design to, more so now that they're on 😆🍋🍋

    An amazing design

    My wife and I are both Knobby addicts! We particularly love the themes of water so both loved this design. I bought both the men's design as I loved the subtle differences in the actual design and the materials. I think I'm finally leaning towards the naturals as the preference. As always, killer comfort and design 👍

    Because who doesn’t love skulls 💀

    My partner got a fright when he caught a glimpse of the glowing skull that night 🤪

    Fun design, very comfy

    The undies are very comfortable and have such a fun design. The colours are vibrant and match the photo

    Comfort and quality

    My 14 year old son got the 5 pack for Christmas the last 2 years and absolutely loves them! Only trunks he wears on rotation and they have lasted so well! Knobby's has fantastic on-line service and a great discount prior to Christmas. Will definitely buy again!
