If you’re new to fitted and adjustable hat styles, the terms A-Frame and 9FORTY can sound a little mysterious. Both are popular silhouettes in the cap world — and if you’re wondering whether they’re adjustable, the short answer is: yes. But there’s more to it than that.
What is an A-Frame Hat?
An A-Frame hat is a style of structured snapback with a slightly higher front panel shaped like the letter “A” when viewed from the side. This gives it a bold, classic look that’s perfect for both casual wear and street style.
-
Adjustment Method: A-Frame hats almost always feature a snapback closure, allowing you to adjust the size to fit most head shapes.
-
Where to Buy: You can find premium A-Frame hats, including exclusive colorways, at HatClub.com.
What is a 9FORTY Hat?
The 9FORTY is a versatile, mid-profile cap often associated with clean, athletic styling. It has a curved brim, structured crown, and sits lower on the head than a 59FIFTY fitted.
-
Adjustment Method: Most 9FORTY hats have a strapback closure (fabric strap with buckle or Velcro) or sometimes a snapback. This makes them easy to size up or down for a comfortable fit.
-
Where to Buy: HatClub.com carries a variety of 9FORTY hats, including team classics and exclusive designs you won’t find anywhere else.
How Adjustable Are They?
Both A-Frame and 9FORTY hats are designed with adjustability in mind, typically fitting head sizes from about 54 cm to 62 cm. If you prefer a looser or tighter fit, you can simply adjust the strap or snaps until it feels right.
Why Choose Adjustable Hats?
-
One Size Fits Most – Great for gift-giving
-
Quick Comfort Changes – Loosen up for a relaxed day or tighten for active wear
-
No Guesswork – You don’t need to know your fitted hat size
Final Answer
Yes — both A-Frame and 9FORTY hats are adjustable. Whether you like the taller front profile of an A-Frame or the sportier, curved look of a 9FORTY, you’ll be able to find an adjustable version that fits your style perfectly — and HatClub.com has one of the best selections of both.
