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.

The softest shirt ever, very nice as a jack of all trades shirt. I will say though the small can fit someone who wears a medium or larger and is pretty baggy on me oddly enough. I'll order an XS and hope it's a little closer to me. Shorts are phenomenal as well. I'm not the biggest fan of the joggers but that's probably just cause the taper and the fit.
