Performance Oxford

in Slate


Introducing the Oxford 2.0

Sprint and catch that train. Bike to your next meeting. Pour that wine with aplomb. Thanks to four-way stretch and a stain-resistant finish, the Proof Performance Oxford rises to every occasion. A 21st century take on the traditional Oxford shirt, this button-down combines the strength of nylon with the comfort of cotton to create a shirt that looks and feels like your favorite everyday Oxford, but moves like a performance tee. We love the structured, athletic fit that retains its shape even after hours of wear, and that this Oxford looks great both tucked and untucked.


  • Four-way stretch for 360 degrees of mobility and 365 days of comfort
  • Innovative midweight fabric combines comfort of cotton with strength and durability of nylon
  • Stain-resistant finish repels wine and pasta sauce for those date night slip-ups
  • Button-down collar
  • Designed in San Francisco, constructed in Shanghai, China, and tested all over the world


  • 70% cotton / 27% nylon / 3% LYCRA®


  • Tailored fit. Take your normal size.

Smart, technical apparel for adventures near and far

Earlier this year we had the opportunity to officially bring Proof into the Huckberry family, and we jumped at the chance given Proof's alignment with the Huckberry mission and ethos. Like the Huckberry guy, the Proof guy lives in the city but lives for adventure, and needs smart, technical apparel that performs at work, on the trail, and in the saddle—and ideally, all in the same day. Inspired by the spirit of the original Proof (formerly known as “Proof NY”), we took the brand back to the drawing board and refreshed the designs, fits, and fabrics with the goal of improving product performance while keeping the price points accessible. In the process, we traveled all over the world to find the best technical apparel manufacturers, and have partnered with blue chip factories from Portugal to Vietnam to the United States.
