Dirty Dog Eyewear TR90 Frames Guide
The Ultimate Guide to TR90 Sunglasses Frames – Built for Every Environment
From alpine glare and desert heat to coastal salt spray and city streets, your eyewear needs to perform wherever you are in the world. Conditions change. Temperatures swing. UV levels spike.
That’s why Dirty Dog builds its high-performance frames using Grilamid TR90 — a material often called “plastic titanium” for good reason.
If you’re tired of replacing broken, warped or brittle sunglasses every season, this guide explains why TR90 is trusted by athletes, adventurers and everyday explorers worldwide.
What Exactly is TR90?
TR90 is a Swiss-developed thermoplastic polyamide, engineered for durability, flexibility and ultra-lightweight performance.
At first glance, it looks like standard plastic.
In reality, it behaves more like a high-tech alloy.
Because of its strength-to-weight ratio and flexibility, TR90 has earned the nickname:
“Plastic Titanium.”
Dirty Dog uses Grilamid TR90 as the backbone of its sport and lifestyle eyewear because it delivers performance without compromise.
Why TR90 is Built for Real-World Conditions
Wherever you live — hot climates, cold winters, humid tropics or dry deserts — your eyewear should adapt, not fail.
1. 100% Memory – The “Bounce Back” Factor
TR90 frames can bend under pressure and return to their original shape.
Sat on them? Dropped them? Packed them tight?
They flex — not snap.
This “memory” makes them significantly more resilient than standard plastics.
2. Lightweight for All-Day Comfort
TR90 is approximately 20% lighter than acetate. That means:
- No pressure points on your nose
- No temple fatigue
- No sliding during long days outdoors
From all-day driving to multi-hour sports sessions, the difference is noticeable.
3. Extreme Temperature Resistance
Cheap plastic frames warp in heat and become brittle in cold. TR90 is engineered to maintain its properties across:
- High heat
- Freezing conditions
- Humid climates
- Dry environments
Whether your sunglasses sit on a dashboard in summer or face cold mountain air, TR90 holds its shape.
4. Hypoallergenic & Skin-Friendly
TR90 is naturally hypoallergenic. If you’ve ever experienced irritation from metal frames or lower-grade plastics — especially during sweat or extended wear — TR90 provides a far more comfortable solution.
Performance on Water, Road & Trail
Impact Resistance
Active lifestyles demand protective eyewear. TR90’s flexibility allows it to absorb and disperse impact energy rather than crack under pressure. This makes it ideal for:
- Cycling
- Running
- Fishing
- Snow sports
- Motorcycling
- Driving
While no material is indestructible, TR90 is significantly more impact-resistant than traditional plastics.
Adaptive Fit
TR90’s natural flex allows frames to contour comfortably to your face. This creates:
- A secure wraparound fit
- Better peripheral protection
- Reduced bounce during movement
- Comfort without excessive grip pressure
Performance without discomfort.
TR90 vs Other Frame Materials
| Feature | TR90 | Standard Plastic / Acetate | Metal |
|---|---|---|---|
| Weight | Ultra-light | Moderate to heavy | Heavy |
| Flexibility | Extreme | Limited | Very limited |
| Heat Resistance | High | Can warp | Conducts heat |
| Impact Resistance | High | Can snap | Can bend permanently |
| Comfort | All-day wear | Heavier feel | Pressure on nose |
If durability, comfort and flexibility matter, TR90 leads.
Built to Support Advanced Lens Technology
Frames are only half the equation.
Dirty Dog lenses are constructed using multiple bonded layers of advanced optical technology, including four UV filters for maximum UV blockage and clarity.
TR90 provides the structural stability required to protect and support these high-performance lenses.
Pro Tips: How to Care for TR90 Sunglasses
Even the toughest gear performs better with proper care.
Rinse After Saltwater Exposure
Fresh water removes salt residue and extends lens life.
Use the Microfibre Pouch
Protects lens coatings and keeps surfaces scratch-free.
Avoid Harsh Cleaners
Mild soap and water are sufficient. Household glass cleaners can damage lens coatings over time.
FAQs About TR90 Frames
What are TR90 sunglasses frames?
TR90 is a high-grade Swiss-developed thermoplastic material known for its lightweight structure, flexibility and durability. Often called “plastic titanium,” it offers 100% memory — meaning it bends and returns to shape — making it ideal for performance eyewear.
Are TR90 frames unbreakable?
No frame material is completely indestructible. However, TR90 is significantly more flexible and impact-resistant than standard plastics or acetate, making it far less likely to snap under pressure.
Can TR90 frames handle high temperatures?
Yes. TR90 has a high heat-deflection temperature and is designed to resist warping in hot environments while remaining stable in cold conditions.
Why are TR90 frames better for sport?
They are lighter, more flexible and safer during impact than metal or rigid plastic frames. TR90 absorbs energy rather than permanently bending or breaking.
Are TR90 frames good for sensitive skin?
Yes. TR90 is hypoallergenic and designed for extended contact with skin, even during sweating or high activity.
How do I clean TR90 sunglasses?
Rinse with fresh water and use a small amount of mild soap if needed. Dry using a microfibre cloth. Avoid harsh chemical cleaners.
