Mission Cooling Performance Hat
Mission's Cooling Performance Hat is a low-profile athletic cap built around the brand's chemical-free cooling fabric, designed to lower surface temperature when wet with water or sweat.
### Overview
The Cooling Performance Hat is a classic-fit cap built around Mission's proprietary evaporative cooling technology, designed to enhance performance without compromising style. It features HydroActive Wet-to-Cool Technology, instantly cooling up to 30 degrees below average body temperature in under one minute and maintaining coolness for up to two hours when activated with water. Mission's fabric technologies are endorsed by the Heat and Safety Performance Coalition at the Korey Stringer Institute.

### Standout Features
- **HydroActive Cooling:** Activates with water in under 30 seconds — simply wet, wring, and wave — and can be reactivated by re-wetting as needed. - **Chemical-Free Fabric:** The cap is machine washable and reusable, with permanent chemical-free cooling technology that will never wash out. - **UPF 50 Sun Protection:** Provides UPF 50+ protection, ensuring excellent UV shielding in both wet and dry conditions. - **Adjustable Fit:** Despite its cooling power, the cap is incredibly lightweight and comfortable, with an adjustable hook-and-loop tab at the back for a personalized fit. - **Odor Resistance:** The fabric resists odors, helping you stay fresh during even the most demanding activities.

### Who It's For
This hat is well-suited for tennis, running, hiking, cycling, yard work, and any activity in hot weather. It's also designed for everyday activities, from cheering on your kids at their games to indoor or outdoor workouts. Anyone who works or spends extended time outdoors in the heat — and wants a practical, reusable cooling solution without relying on chemical treatments — will find this a strong option.

### Important Considerations
- **Cooling requires water:** Even when dry, the ventilated material keeps the cap cooler than a regular hat, but the strongest cooling effect happens when activated with water — so you'll need access to water to get full performance. - **Cooling duration is limited:** The effect lasts up to two hours per activation, meaning you may need to re-wet the hat during longer outings. - **Sizing can run small:** A reviewer noted the hat was smaller than expected and required an exchange for a larger size — check sizing guidance before ordering. - **Pricing:** The Cooling Performance Hat is listed from $9.99 up to $29.99 on Mission's site, depending on color and availability, making it an accessible entry point into Mission's cooling lineup.
Key features
- Chemical-free cooling fabric
- UPF 50 sun protection
- activates with water/sweat
- athletic low-profile design
Cooling that activates on contact with moisture — no chemicals, no gimmicks, just physics.
What stands out
- Chemical-free cooling technology activates with water or sweat, making it practical for outdoor workouts and hot-weather sport
- UPF 50 sun protection adds meaningful defence against UV exposure during extended outdoor activity
- Low-profile athletic design sits close to the head, compatible with helmets and headphones
- Cooling mechanism requires no refrigeration or pre-treatment — just moisture
What to weigh
- Cooling effect depends entirely on moisture availability, so performance may be limited in dry heat without pre-wetting
- Low-profile fit may not suit those who prefer a structured or high-crown cap
- Longevity of the cooling fabric's effectiveness over many wash cycles is not independently verified
Great fit if
- Runners, cyclists, or hikers who train in hot, humid conditions where sweat activates the cooling effect
- Those seeking sun protection without chemical sunscreen on the head
- Athletes who need a hat compatible with helmets or other headgear
Skip it if
- Anyone training in arid, low-humidity environments where sweat evaporates too quickly to sustain the cooling effect
- Those who prefer a traditional structured cap silhouette
