Main Hat Types
-
A fitted hat is a closed-back cap sold in exact sizes instead of using an adjustable strap or snap. The most popular example of a fitted hat is the New Era 59FIFTY series. Find your perfect fitted hat at capworld.store.
-
A snapback hat is an adjustable cap with a plastic snap closure at the back. Popular types of snapbacks are the New Era 9FIFTY or 9FORTY A-Frame snapbacks.
-
An A-Frame hat uses a taller, more peaked front panel that creates a sharper front profile above the brim. Many buyers choose A-Frames because they keep the ease of a snapback or adjustable closure while delivering a stronger shape from the front, especially in streetwear-leaning team hats. Many basic and special A-Frame hats can be found at capworld.store
-
A dad hat, often called a strapback, is a relaxed cap with an adjustable rear closure and a softer overall feel than a structured snapback. It usually has a curved brim, lower crown, and broken-in everyday look, which is why it stays popular for casual wear and easy styling. Many dad caps can be found at capworld.store
-
A trucker hat combines a structured front panel with mesh back panels for airflow. That design gives you the bolder face of a snapback with more ventilation, which is why truckers work well for warm weather, outdoor wear, and casual streetwear styling. Many trucker hats can be found at capworld.store
-
A bucket hat is a soft, downward-brim hat with full-circumference coverage around the head. It is popular for casual wear, festival styling, travel, and warmer weather because it gives more sun coverage than a standard baseball cap. Team bucket hats can be found on capworld.store.
-
A fisherman hat is a short-brim, bucket-adjacent silhouette with a simple utility feel and casual shape. Depending on the brand, it may look like a tighter, cleaner bucket or a more rugged outdoor hat, which makes it popular for warm-weather and streetwear styling. More team fisherman hats can be found on capworld.store.
-
A stretch-fit hat uses flexible materials and a size range instead of a snap closure or exact fitted measurement. It gives you a more streamlined look than an adjustable cap while offering more forgiveness than a true fitted, which is why stretch-fit styles are popular for comfort-first everyday wear. Many basic and special stretch-fit hats can be found at capworld.store
-
A baseball cap with a Velcro strap is an adjustable cap that uses a hook-and-loop closure in the back instead of snaps, a buckle, or a fitted size. It is easy to adjust and usually has a simple everyday fit.
This style is a good option for shoppers who want quick sizing flexibility without the sharper look of a snapback. -
A straw hat is a warm-weather hat made with straw or straw-like material for airflow, shade, and a lighter seasonal feel. Team straw hats are popular for summer games, outdoor events, beach days, barbecues, and sunny weather.
Compared with a fitted or snapback, a straw hat is less about a structured streetwear look and more about comfort, shade, and seasonal wear. -
Team sun headwear includes hats made for sunny weather, outdoor events, and warm conditions. This can include straw hats, bucket hats, fisherman hats, performance caps, and other styles that give more shade or airflow than a standard fitted or snapback.
These styles are useful for game days, beach trips, golf, workouts, festivals, and everyday summer wear.
Brims, Crowns & Hat Shape Terms
-
A curved brim hat has a visor that is already bent or designed to be worn with a natural curve. Curved brims usually read more casual and ready-to-wear than flat brims, which is why they show up often on dad hats, ’47 styles, 9FORTYs, and other everyday caps. Find your perfect curved hat at capworld.store.
-
A flat brim hat has a straighter visor that has not been fully curved at the factory. Flat brims are strongly tied to fitted hats, snapbacks, and modern streetwear because they make the hat look cleaner, sharper, and more architectural from the front. Many basic and special flat brim hats can be found at capworld.store
-
Low profile describes a hat with a lower crown height and a closer-to-the-head fit. Compared with taller structured caps, low-profile hats feel subtler and less boxy, which is why many casual buyers prefer them for everyday wear.
-
A high crown hat has a taller front and more height above the forehead. High crown styles usually look bolder, more structured, and more noticeable from the front.
Many snapbacks, A-Frames, and structured fitted hats use a higher crown to create a sharper streetwear or collector-style shape. -
A structured crown means the front of the hat is reinforced so it holds its shape instead of collapsing. Structure matters because it changes the entire look of the cap: structured hats appear sharper and more defined, while unstructured hats look softer and more relaxed. Many structured baseball caps can be found at capworld.store.
-
The underbrim, also called the undervisor, is the underside of the brim. On modern team hats, underbrim color is often used as a design detail. It may be grey for a classic look, green for heritage cues, or custom colors to tie into a patch, logo, or outfit.
-
The crown is the main upper part of the hat that sits around your head. Crown shape affects how tall, deep, structured, or relaxed a hat looks when worn.
A taller crown can create a bolder front profile, while a lower crown usually feels more subtle and closer to the head. -
An unstructured hat does not have stiff reinforcement in the front crown, so it feels softer and more relaxed. The front of the hat can naturally fold or sit closer to the head instead of holding a firm shape.
Dad hats and many relaxed caps are often unstructured, which is why they feel broken-in and casual from the first wear. -
Hat panels are the fabric sections that make up the crown of the cap. Many baseball caps use multiple panels sewn together to create the final shape.
Panel layout can affect how the hat fits, how the front logo sits, and how structured or smooth the crown looks from the front.
Design & Collector Terms
-
A side patch hat is a cap that adds a commemorative patch, such as a World Series, anniversary, stadium, or event logo to the side panel. Side patches are popular because they turn a standard team hat into something with more story, more visual detail, and often more collector appeal. More hats with side patches can be found on capworld.store
-
A reverse logo hat flips or alters the standard team logo placement so it reads as an intentional design twist rather than a classic team issue. In practice, reverse-logo hats sit at the intersection of sports identity and fashion, which is why they became popular in modern fitted and streetwear culture.

An Authentic Collection hat refers to the official On-Field collection associated with Major League Baseball and New Era. These hats are tied to the same product family worn by players or built from the same official program, which is why the Authentic Collection name carries more weight than a generic team cap label. More On-Field hats can be found on capworld.store
New Era Style Terms
-
The New Era 59FIFTY and 9FIFTY share a family resemblance, but they are built differently. The 59FIFTY is New Era’s flagship true fitted with a closed back and exact sizing, while the 9FIFTY is the classic snapback version that mimics the 59FIFTY’s shape but uses an adjustable closure.

-
A 9FIFTY and a 9FIFTY A-Frame are both snapbacks, but the front shape is different. The standard 9FIFTY follows the familiar six-panel snapback silhouette, while the 9FIFTY A-Frame uses a taller, more pinched front panel that creates a sharper peak above the brim.

-
The 9FORTY is New Era’s curved-visor adjustable silhouette, while the 9FORTY A-Frame keeps that general family but adds a higher, more defined front shape. In simple terms, the A-Frame version is the bolder-looking one; the standard 9FORTY is usually the more classic everyday fit.

A New Era 59FIFTY is New Era’s classic true fitted hat. It has a closed back, structured crown, flat brim, and exact numeric sizing instead of an adjustable closure. The 59FIFTY is one of the most popular fitted silhouettes for sports fans, collectors, and anyone who wants a clean, structured cap.
-
A New Era 9FIFTY is New Era’s classic snapback style. It has a structured crown and a snapback closure, giving it a similar front shape to a fitted hat while still allowing the size to be adjusted.
The 9FIFTY is a good choice for shoppers who like the bold look of a fitted hat but want more flexibility in the fit. -
A New Era 9TWENTY is a relaxed, adjustable cap with a softer, more casual fit. It usually sits lower on the head than taller structured styles and is made for easy everyday wear.
The 9TWENTY is a good choice for shoppers who want a comfortable, broken-in feel with an adjustable closure, curved visor, and relaxed front panels. -
A New Era 9FORTY is an adjustable cap with a curved brim and a more everyday fit. It usually feels more casual than a 59FIFTY fitted or 9FIFTY snapback because the shape is easier to wear right away.
The 9FORTY is a strong option for shoppers who want a team hat with a curved brim, adjustable fit, and cleaner daily-wear look. -
A New Era 9FORTY A-Frame keeps the adjustable, curved-brim feel of a 9FORTY but adds a taller, sharper A-Frame front shape. It gives the hat more structure and a stronger front profile than a standard curved-brim adjustable cap.
This style works well for shoppers who want an adjustable hat that still has a bold streetwear-inspired shape. -
A New Era 39THIRTY is a stretch-fit cap with a closed back, curved visor, and flexible fit. It does not use a snapback or strap closure, but it has more give than a true fitted hat.
The 39THIRTY is a strong option for shoppers who want a clean, athletic look with stretch comfort instead of exact fitted sizing.
'47 Brand Style Terms
-
A ’47 Clean Up cap is one of the brand’s best-known casual silhouettes: relaxed, unstructured, adjustable, and usually finished with a curved visor. It is popular because it feels easy from the first wear and works well for shoppers who want a softer everyday team hat instead of a tall structured crown. More '47 Clean up dad caps can be found on capworld.store.
-
A ’47 Hitch snapback uses a mid-fit crown and snapback closure, giving it more structure than a relaxed cap without going all the way to the deepest high-crown look. It has become popular because it sits in the sweet spot between casual wearability and a stronger front profile. Shop our Hitch caps at capworld.store
-
A ’47 MVP hat is a structured cap known for a shallower, more compact fit than some taller snapback silhouettes. It works well for buyers who want a cleaner team-hat shape with structure, but without the extra height of a deep-crown fashion cap.

A ’47 Captain snapback is one of the brand’s deepest and most structured silhouettes, built with a flat brim and a stronger front wall than relaxed caps. It is popular with shoppers who want a bold front-facing shape that feels closer to classic snapback and streetwear territory.

The ’47 Clean Up and the ’47 Hitch serve different jobs. A Clean Up is relaxed, unstructured, and strapback-like, made for easy everyday wear. A Hitch is more structured, uses a snapback closure, and gives you a stronger front profile without getting as deep as some high-crown caps.

Mitchell & Ness Style Terms

Quick Hat Comparisons
-
The biggest difference between a fitted hat and a snapback is sizing. A fitted hat comes in exact sizes and has no rear adjustment, while a snapback uses an adjustable plastic closure that lets one hat cover a range of head sizes. That difference also changes the look: fitteds usually feel cleaner and more tailored, while snapbacks offer
more flexibility.Browse both our most popular snapback and fitted hats at capworld.store
-
A stretch-fit hat and a fitted hat can look similar from the back because neither uses a snap closure, but they fit differently. A true fitted uses an exact numeric size, while a stretch-fit uses elastic construction to cover a size range with a little more forgiveness.

A curved brim hat feels more casual and ready-to-wear, while a flat brim hat looks cleaner, sharper, and more fashion-forward. The choice is less about right or wrong and more about the effect you want: relaxed everyday wear versus a stronger structured silhouette.
-
A structured hat has reinforcement in the front crown so it holds its shape. An unstructured hat is softer and more relaxed, with less support in the front.
Structured hats usually look sharper and more defined. Unstructured hats usually feel more casual, broken-in, and easy to wear. -
A regular snapback usually has a classic multi-panel front shape. An A-Frame hat has a taller, more peaked front panel that creates a sharper shape above the brim.
Both can be adjustable, but the A-Frame has a stronger front profile and usually feels more streetwear-focused. -
A snapback uses a plastic snap closure in the back, while a strapback uses an adjustable fabric, leather, or buckle-style strap. Both are adjustable, but they create different looks.
Snapbacks usually feel more structured and streetwear-focused. Strapbacks usually feel softer, more classic, and more casual. -
A bucket hat usually has a soft, downward brim that goes around the entire head. A fisherman hat is similar but often has a shorter, more utility-style brim and a cleaner outdoor-inspired shape.
Both are good for casual wear, warm weather, and sun coverage, but fisherman hats usually feel a little more compact and functional.
