Many people only look at the fabric, embroidery, and logo when buying hats. What truly determines whether the brim can maintain its crispness is the unseen inner lining. The same style and fabric, but with a different brim material, can result in completely different conditions after a few months.
Today, let’s discuss what’s inside the brim from a factory perspective.
1. Resin Impregnated Lining
This is currently the most common brim material.
Advantages:
- Moderate cost
- Stable shaping effect
- Suitable for most baseball caps
Drawback: If frequently washed in high-temperature water, the resin will gradually lose its hardness, and the brim’s support will decrease. This is why many hats feel increasingly soft after a few washes.
2. PE/PP Brim Plate
Many branded hats upgrade to use PE or PP brim plates.
Characteristics:
- Fast rebound speed
- Moisture resistance
- Maintains its curvature even after prolonged wear
- Longer lifespan
Factories usually choose different thicknesses depending on the hat shape, so the feel of each hat will vary.
3. EVA Brim Lining
EVA’s biggest advantage is its lightness, and it is used in many sports caps and Korean-style caps.
Advantages:
- Lightweight
- Good toughness
- More comfortable to wear
Compared to PE board, EVA is generally softer and more suitable for lightweight products.
How Do Factories Choose Brim Materials?
Many customers ask: “Is harder always better?”
Actually, factories value fit more:
- Washed retro hats need a natural brim curve.
- Trendy flat-brimmed hats need better support.
- Sports hats focus more on weight and rebound.
Different products have completely different requirements for brim materials.
A Simple Way to Judge Brim Quality
After receiving the hat, gently press the brim. The faster it recovers after releasing, the more stable the brim support material and structure are usually.
Then observe the edge of the brim. If there is delamination, bulging, or glue separation, it will be more likely to affect the shaping effect during later use.
Final Word from Aung Crown
Many people think that the quality of a hat is only judged by the outer fabric and embroidery. As a factory that has been making hats for over 20 years, I pay more attention to the inner lining.
Whether the brim can hold its shape is hidden in the unseen place.
