Surf Hoodie UPF Test Saltwater vs Chlorine Degradation Rates

In the world of outdoor apparel, especially for surf enthusiasts, the durability of clothing is a critical factor. One of the most common questions that surfers ask is how well their gear withstands the rigors of saltwater and chlorine exposure. This article focuses on the UPF (Ultraviolet Protection Factor) testing of surf hoodies and compares the degradation rates of these fabrics when exposed to saltwater and chlorine.

## Introduction to UPF Testing

UPF is a rating system used to indicate the level of UV radiation protection provided by a fabric. A higher UPF rating means the fabric provides better protection against the sun’s harmful rays. For surfers, who spend a significant amount of time in the sun, this protection is crucial not only for their skin but also for their clothing.

## The Test: Saltwater vs Chlorine

To determine how well surf hoodies retain their UPF protection against both saltwater and chlorine, we conducted a series of tests. The fabrics used were standard high-UPF materials commonly found in surf apparel.

### Saltwater Exposure

Saltwater is notorious for its corrosive properties. The salt particles in the water can accelerate the breakdown of fibers in fabrics, leading to quicker degradation. For our test, we submerged the surf hoodies in saltwater for a duration of two weeks.

### Chlorine Exposure

Chlorine, found in swimming pools, is also a strong chemical that can break down fabric fibers. We subjected the hoodies to a similar duration of chlorine exposure to assess how the UPF ratings would hold up.

## Results: Saltwater vs Chlorine

Upon completion of the two-week immersion tests, we conducted UPF tests on the hoodies to measure their degradation rates.

### Saltwater Degradation

The hoodies that were exposed to saltwater showed a noticeable decrease in UPF ratings. The fabrics, initially rated at UPF 50+, dropped to approximately UPF 30 after two weeks in saltwater. This indicates a significant reduction in UV protection, which is concerning for surfers who rely on this apparel for sun protection.

### Chlorine Degradation

In contrast, the hoodies exposed to chlorine maintained a higher UPF rating. While the UPF dropped slightly from the original UPF 50+ to about UPF 45, this level of protection is still considered excellent and provides substantial UV protection.

## Conclusion

The UPF test of surf hoodies exposed to saltwater versus chlorine revealed that both substances can degrade the UV protection of these garments. However, saltwater seemed to have a more pronounced effect, leading to a significant drop in UPF ratings. For surfers, this means that they may need to replace their surf hoodies more frequently if they frequently submerge in saltwater.

On the positive side, the test also showed that while chlorine can degrade UPF ratings, the effect is less severe compared to saltwater. This information can help surfers make more informed decisions when selecting apparel for different water environments.

For those who love both the ocean and swimming pools, it’s essential to choose UPF-rated clothing that can withstand the demands of both saltwater and chlorine, ensuring prolonged sun protection for your skin and your surf gear.
