They primarily offer superior moisture-wicking and quick-drying to keep you cool and dry. They include UPF 50+ UV protection and provide muscle compression and support.

CoolMax is a high-performance polyester fiber with a unique cross-section (like four channels). This structure rapidly wicks moisture (sweat) away from your skin to the fabric’s outer layer, where it evaporates quickly, creating an evaporative cooling effect and regulating body temperature.

Yes, the sleeves designed for outdoor use feature a UPF 50+ rating, which means they block about 98% of harmful UVA and UVB rays, offering more consistent sun protection than sunscreen.

They are ideal for any outdoor or high-intensity activity where you sweat and need sun protection, such as running, cycling, golfing, basketball, hiking, and yard work.

They are generally easy to care for. You should machine wash in cool water with a mild detergent. Avoid using fabric softeners or chlorine bleach, as these can damage the elasticity and moisture-wicking properties. Air drying is usually recommended.

For general sports and sun protection, most people can wear them comfortably for 8-12 hours. If you are wearing them for a medical condition like lymphedema, follow your physician’s specific guidance on duration.

Replace your sleeve when it starts to slide down during activity, when the elasticity drops noticeably, or when you observe reduced compression. Quality sleeves are durable, but compression will diminish over time and repeated washing.

The CoolMax fabric itself is primarily for moisture-wicking. However, many brands incorporate a separate anti-odor or anti-microbial treatment (like CoolMax FreshFX) into the fabric blend to inhibit the growth of bacteria that cause odor.

It is not recommended. For cooling, the material needs to be in direct contact with your skin to effectively wick sweat and facilitate evaporative cooling. Wearing it over a shirt will trap heat and reduce the wicking performance.

CoolMax (Polyester) excels at fast moisture transport and drying speed. Nylon is often more durable and stretchy. Bamboo/Rayon is softer and naturally anti-bacterial but usually less effective at rapid wicking. CoolMax is the established benchmark for high-performance moisture management.

Generally, yes. CoolMax fabric is lightweight and soft. For sensitive skin, look for sleeves without rough seams (seamless construction). For new tattoos, they offer excellent UPF 50+ UV protection, which is crucial for healing.

Yes. They are excellent for driving (UV protection on the window arm) and for outdoor occupations to prevent sunburn and heat fatigue. Some industrial-grade sleeves also incorporate cut-resistant fibers with the CoolMax for enhanced protection.

UV protection (UPF) is typically woven into the fibers and is durable. The compression and elasticity will gradually decrease over time and with washing, especially if you use fabric softeners, which should be avoided.
