The Story Behind The Cap

For The Competitor In All Of Us

We are aiming for excellence. This cap is no exception. Designed specifically for PGA TOUR winner Harry Hall and his pursuit for championships, this cap is made with quality materials that perform above expectations.

“Excellence is never an accident. It is always the result of high intention, sincere effort, and intelligent execution." – Aristotle Greatness

Making its debut at the Masters in Augusta, Georgia, this cap pays a deep respect to the history of the event while delivering on the required characteristics of a 3 season cap. It was imperative that we design a cap that matches the elegance and clean look that comes with this prestigious event, but also provides next level comfort, durability, and performance. This cap is made with 100% tropical wool, the same fabric the green jacket is made of, and is accented with leatherette under the brim that resembles that of a traditional golf glove.

This might sound counterintuitive, but "tropical wool" is a specific type of wool fabric designed for warm weather. Its lightweight and breathable, with a smooth, elegant finish that maintains a professional and refined appearance. This porous weave allows for exceptional air permeability, making it surprisingly breathable. It also boasts natural moisture-wicking properties and excellent drape, resisting wrinkles better than linen or cotton and keeping you dry in the heat.

Our caps are sized in CMs to get the best fit. For help measuring your head, reference this step-by-step guide.

*Not all caps come in XS

Tropical wool represents the pinnacle of performance-oriented craftsmanship, combining the natural sophistication of fine wool with a weave engineered for warmer climates and year-round wear. Crafted from high-quality wool fibers spun into lightweight yarns, tropical wool is woven in a way that promotes airflow while maintaining the structure, durability, and refined appearance wool is known for.

Working with this material requires precision, as its lighter construction demands careful tailoring to preserve shape and performance. The result is a fabric that resists wrinkles, breathes exceptionally well, and remains comfortable through long days of wear.

Frequently Asked Questions

Step 1: Wrap the soft tape, string, or cord around your head above your ears and eyebrows, where your cap usually sits.

Step 2: Double check to make sure the tape comes down far enough at the back of your head, hitting in the right spot.

Step 3: Take note of your measurement in CMs. If using a string or cord, mark where it meets so you can measure it using a traditional tape measure.

Step 4: Refer to the sizing chart above to see where you land.

For our comfort fit flex back caps, we always recommend sizing down. For our fitted caps, size up for a loose fit and size down if you prefer snug. Caps will usually stretch slightly, but rarely do they shrink.

Unfortunately, there is no universal sizing, so a Medium for one brand might be a Small for another. We highly recommend you measure your head to ensure you have an accurate size before ordering from Peaky Hat.

All of our caps are warehoused and shipped directly from Peoria, Illinois. If you place your order Monday through Friday before noon Eastern time, it ships out the exact same day.

We offer a 45-day window for returns and exchanges. Buying a cap online should be rewarding and enjoyable, not a risk. There is a $5 exchange fee and a $10 refund fee. If you ever have an issue, reach out to support@peakyhat.com and Ryan will handle it personally.

Our fabrics are sourced globally—from US mills to Scottish Harris Tweed and UK linens. The final stitching is done by a highly skilled team in Yiwu, China (the same district that produces caps for Stetson and Goorin Bros). We are completely transparent about this because we choose quality over optics, every time.
