The Complete Guide to UPF 50+ Fishing Shirts – What OEM Buyers Need to Know

Why UPF 50+ Fishing Shirts Are Essential for Your Brand

If you're sourcing fishing shirts for your brand, one question comes up more than any other: what level of sun protection actually matters to your customers? The answer is UPF 50+. Unlike SPF (which measures sunscreen), UPF measures how much UV radiation penetrates a fabric. A garment rated UPF 50+ blocks 98% of both UVA and UVB rays — and it does so without reapplication, without washing off, and without the chemicals found in sunscreen.

At DERY, we've been manufacturing UPF 50+ fishing shirts for 26 years. Here's what we've learned about what makes a fishing shirt perform — and what you should look for when choosing a manufacturer.

UPF 50+ vs. SPF – Why the Difference Matters

Many articles confuse SPF with UPF. Understanding the distinction is critical if you're sourcing performance fishing apparel:

UPF measures how much UV radiation penetrates the fabric itself. A UPF 50+ rating means only 1/50th (2%) of UV radiation reaches the skin. This protection is woven into the fabric structure — it doesn't wash off or wear out like sunscreen. SPF, by contrast, measures how long sunscreen protects skin before needing reapplication. For clothing, always look for UPF, not SPF.

Most DERY fishing shirts — including our long sleeve camo fishing shirts and UPF 50+ polo shirts — are tested and certified with a UPF 50+ rating that lasts the lifetime of the garment.

What to Look for in a Fishing Shirt Manufacturer

When sourcing custom fishing shirts, look for these capabilities:

- Fabric expertise: Can they explain the difference between 180gsm and 150gsm polyester-spandex for different climates?
- UPF certification: Do they have third-party testing (like SGS) to validate their UPF claims?
- Customization options: Sublimation printing vs. screen printing — which suits your market?
- MOQ flexibility: Can they start with 50 pieces for a test run?
- Sample lead time: 1–2 weeks is standard for serious manufacturers

These are questions we answer every day at DERY. Our performance long sleeve fishing shirts, for example, are available in custom Como camouflage patterns with your brand's colors, your label, and your packaging.

Fabric Matters – The 88/12 Polyester-Spandex Standard

The industry standard for performance fishing shirts is an 88% polyester / 12% spandex blend at 160gsm. Why this specific ratio?

- Polyester provides quick-dry moisture-wicking — pulls sweat away from the skin
- 12% spandex delivers 4-way stretch — essential for unrestricted casting movement
- 180gsm balances durability with lightweight comfort — substantial enough for all-day wear, light enough to pack down to pocket size

We offer fabric weight variations for different markets — lighter 150gsm for extreme heat, heavier 200gsm for premium-feel products. Every fabric option can be paired with UPF 50+ protection and all-over sublimation printing for custom camo patterns like the popular Como series.

Custom Camo Patterns – Why Sublimation Beats Screen Printing

When customizing fishing shirts with camouflage patterns, the printing method directly affects product quality and longevity.

Sublimation printing infuses the dye into the polyester fibers at the molecular level. The pattern becomes part of the fabric — it won't peel, crack, fade, or stiffen, even after dozens of saltwater washes. Screen printing sits on top of the fabric surface and degrades over time, especially on stretch fabrics.

DERY offers both methods, but for performance fishing apparel, we recommend sublimation for camo patterns. Our Como pattern and honeycomb camo designs are among the most requested by brands launching their own fishing apparel lines.

Frequently Asked Questions

Q: What is the difference between SPF and UPF in fishing shirts?
A: SPF measures sunscreen protection. UPF measures fabric protection. Fishing shirts use UPF ratings. Always look for UPF 50+ on clothing labels.

Q: How long does UPF 50+ protection last in a fishing shirt?
A: Unlike sunscreen, UPF protection in tightly woven polyester fabric does not wash out. The UPF rating is achieved through the fabric's fiber density, not a chemical coating. With proper care (no bleach, no fabric softener), it lasts the life of the garment.

Q: Can I get a custom camo pattern in my brand's colors?
A: Yes. DERY offers custom all-over sublimation printing. You can choose from 100+ existing patterns (including Como) or provide your own artwork. Custom color matching is available.

Q: What is the MOQ for custom fishing shirts?
A: Standard MOQ is 100 pieces mixed sizes and colors. For single-color orders, 50 pieces per color. Sample orders: 1–5 pieces with 1–2 week turnaround.

Q: How do I know if a manufacturer's UPF claim is real?
A: Ask for third-party test reports. DERY provides SGS UPF certification upon request. Any serious manufacturer should be able to provide independent verification.
