Different Types of Cap Fabrics

There are so many types of hats and caps in use these days that it could get pretty confusing for someone new to figure out what kind of fabric they want for their preferred type of cap.

But worry not. Expert Cap designers and hat makers at Delicate Source are here to help guide you through the whole process to know the available cap fabrics better and make the best decision for your brand. To begin with, two types of fabrics are used in every cap, which are:

  • Interior portion fabrics
  • Exterior portion fabrics

These materials vary, depending on the fitting, the season and the weather.

For example, winter caps are made from wool, as it helps keep the head warm in the cold while making you look fashionable.

Another example is that caps made for sports and athletic purposes are usually made from cotton as it absorbs sweat and keeps your head cool, making it one of the breathable cap fabrics.

Most Popular Cap Fabrics


It is a synthetic fiber, made artificially and in perhaps the most widely used cap fabric. In the modern cap making process, polyester is preferred due to its durability and flexibility. It is made from recycled plastic, making it a greener and sustainable option. Polyester is not preferred due to its eco-friendliness but because it is also durable and water-resistant, making it ideal for sports caps. On top of all that, it is also very cost-effective, making it highly affordable.

Moreover, its moisture absorption quality makes it ideal for keeping the skin dry, making it easy to wear them during a hot summer day.


Nylon is another type of fabric preferred in making lightweight caps, such as capos for the summer season. Like polyester, it is also recycled and made from plastic, giving it similar properties to polyester, which also includes being a breathable and affordable fabric.

However, a distinct feature of nylon is that it does not shrink, which helps it keep its shape and fit.


Cotton is perhaps the most popular among natural cap fabrics. However, it is preferred to use it with some other fabric because pure cotton tends to get a little more expensive. For that very reason, most of the time, cotton is used on polyester and nylon caps for embroidery and putting logos since it may cost a fortune to make pure cotton caps in wholesale quantity.

What makes cotton so popular is that it is soft and highly breathable, making it a customer favorite. Moreover, pure cotton caps prevent skin irritation no matter how sweaty they may get. It helps insulate heat and store moisture, so it is used in hats and makes headbands used during a workout or playing sports.


Wool is often associated with knitted caps and hats. However, it is most certainly not the case. Most classic hats are usually made from pure woolen, which is 100 per cent wool. Wool is widely used in making baseball caps and military berets.

Moreover, we already know how popular wool is for making winter hats that can keep you warm during cold nights.


Primarily used in making the sturdy brims of formal hats, buckram is a stiff material with high durability. Therefore it is used in making the visors of caps and outer rings of formal and traditional hats that are durable and stiff.

Buckram is not directly displayed but concealed in the main fabric of the hat, letting it work from behind the curtain. Essentially buckram is also made from different types of materials such as:

  • Cotton
  • Horsehair
  • Wood

All of these makeup for durable and sturdy buckrams, which we can rely on to protect us from the sun and keep their shape and integrity, even after being wet or soaked.
