The Baja Flannel Shirt Jacket: American-Made Quality, Built for Spring and Beyond

At Signature Innovation Group, we believe every piece of clothing should tell a story. Our Baja Flannel Shirt Jacket is no exception. Inspired by the vibrant Mexican culture we grew up alongside in Fontana, CA, this shirt jacket is a modern take on timeless tradition.

We took the rich textures of ponchos, hoodies, and serapes, and infused them into a durable, American-made flannel that’s perfect for transitional weather. Built for spring, this piece blends heritage and function, making it a staple for men who demand both comfort and style.

Built for Versatility

The Baja Flannel Shirt Jacket is designed to be your go-to layer when temperatures shift. Made from a heavy 9oz textured cotton, it provides warmth without bulk and softens beautifully over time. Whether you’re layering it over a tee on a cool morning or buttoning it up as the evening breeze rolls in, this shirt jacket adapts to your day.

Function Meets Style

Every detail of this American-made flannel was built with purpose. Snap buttons transition from luxury to necessity, making it easy to throw on and off. Side gussets add flexibility while maintaining a polished, untucked look. The rich burgundy yarn-dyed dobby material gives it a rugged yet refined feel—equally at home on city streets or weekend getaways.

Available in Three Distinct Colors

To suit your personal style, the Baja Flannel Shirt Jacket comes in three distinct colors:

• Sage: A muted green that pairs well with both neutral and bold tones. View the Sage variant here.
