Buff CoolNet UV+ Review (2026)

Name: Buff CoolNet UV+
Brand: Buff
Price: 25.00 USD
Availability: InStock
Rating: 9.1 (1 reviews)

Buff built the CoolNet UV+ specifically around a fabric treatment that creates a genuine cooling sensation against the skin, distinct from the standard Original's fabric — testers consistently note a real, noticeable difference in perceived coolness, particularly when the gaiter is dampened with water or sweat, which activates the cooling effect more strongly.

What Works

CoolNet fabric is specifically engineered to feel cool to the touch, a genuine and noticeable sensation versus a standard Buff
UPF 50+ rating is slightly higher than the standard Original Ecostretch
Same seamless multi-way construction as Buff's classic design, so it wears and functions identically

Limitations

The cooling sensation fades somewhat once the fabric is fully saturated with sweat and needs to be re-wetted
Offers essentially no insulating warmth, so it's a summer-specific piece rather than a year-round one

What Sets It Apart

It carries a slightly higher UPF 50+ rating than the standard Original and is aimed squarely at hot-weather hiking, running, and cycling where sun and heat management matter more than any warmth.

Who This Is For

The CoolNet UV+ is right for: hikers in consistently hot, sunny climates who want an active cooling effect rather than just sun blocking, trail runners and cyclists who benefit from re-wetting a gaiter for cooling during exertion, and anyone who already owns a standard Buff and wants a dedicated summer-specific upgrade.

Common Questions

Does the CoolNet UV+ actually feel cooler than a regular Buff?

Yes — testers consistently report a genuine, noticeable cooling sensation from the CoolNet fabric treatment, especially when the gaiter is wetted, which is a real fabric-engineering difference rather than just marketing.

How long does the cooling effect last?

It's strongest when the fabric is damp from sweat or added water and fades as it fully dries out, so re-wetting periodically during hot-weather activity maintains the effect.

Can the CoolNet UV+ be used in cold weather?

It offers minimal insulating warmth on its own, so it's best treated as a summer and hot-weather piece rather than a cold-weather layer.
