      Everyday Shorts and swim trunks  all-in-one.

      A brand born from travel.

      We’re Mariah & Tray—two travelers who met while studying abroad in Thailand. The more we traveled, the more packing felt like a compromise. Gym clothes were built to sweat in, not to live in. Loungewear felt sloppy. Everyday clothes felt stiff the second we moved.

      So we built Bamboo Ave and pioneered Travel Leisure—versatile, insanely comfortable gear made for movement, adventure, and the in-between moments that make every day better.

      Now, tens of thousands wear Bamboo Ave to travel better, move freer, and stay ready for whatever’s next.
