Field Jacket

in Dark Navy


A smart, high-performing winter jacket wrapped up in a classic design

Inspired by arguably the most famous field jacket in history, Proof put a modern spin on the M-65, which is named after the year it was first introduced into U.S. military service. Designed to be your go-to city jacket, the Proof Field Jacket is a smart mid weight option that pairs perfectly with a button-down or sweater, and is versatile enough to take you from day into night, and work into weekend. To combat the wide spectrum of winter weather, this jacket is constructed with outer-shell that’s water-resistant, 80 grams of breathable PrimaLoft® insulation that retains its warmth in wet conditions, and a storm hood that zips away when not needed. We love the modern fit and thoughtful design details — like how you can access all five pockets, including a secret stash pocket for your phone or travel documents, without unzipping your jacket. It’s why this refined cold-weather staple has quickly become a favorite here at HBHQ.


  • A covert storm hood zips away when not needed
  • You can access all five pockets — including a secret stash pocket for your phone or travel documents — without unzipping your jacket
  • Two front field pockets house two additional hidden hand pockets
  • A protected zipper stops right below your belly button to give you greater range of movement; it's the jacket equivalent of having the option to unbutton your top button for comfort
  • Designed in San Francisco, constructed in Ho Chi Minh City, Vietnam, and tested all over the world


  • 90% polyester / 10% cotton outer-shell is water and stain resistant
  • PrimaLoft® Silver 80g insulation retains its warmth in wet conditions, and was originally developed to serve the needs of the U.S. Army, who desired a water resistant, synthetic alternative to goose down
  • Matte black snap buttons
  • Matte black YKK zippers


  • Field Jacket length reaches just below your pant pockets
  • Smart, athletic fit

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.
