CoreCooling Wrist-Sleeves

Tri-Excellence CoreCooling products are designed to keep athletes’ core body temperatures lower during training and competitions. The collection consists of:

• Base-layer with 4 cooling pockets
• Arm-sleeves (left and right) with 1 pocket on each arm
• Wrist-sleeves (left and right) with 1 pocket on each wrist
• Head-band with 1 pocket

The CoreCooling products use advanced cooling technologies, including high-absorbent blue fabric for evaporation cooling and cooling patches that provide stable temperatures. Available cooling patches include Orange Patches (6°C / 44°F) and Blue Patches (15°C / 59°F), which fit into the pockets and provide cooling for up to 80 minutes, depending on weather conditions. These patches are reusable, bio-based, and USDA and REACH certified.

There are 3 special innovative cooling techniques incorporated in the Tri-excellence CoreCooling products

The CoreCooling Fabric: this is a special fabric (the blue fabric) that stimulates evaporation cooling. This fabric is highly absorbent. Just soak it in water for a moment, squeeze it and it is ready to provide several hours of cooling. This fabric is designed to soak and keep moisture (from sweat or water) in the fabric and the special design of the fabric allows for a better evaporation cooling of the skin.

The Cooling Patches: These patches give a constant cooling temperature. The orange patch a constant temperature of 6 degrees Celsius (44 degrees F), the blue patch a constant temperature of 15 degrees Celsius (59 degrees F). The patches cool the blue fabric continuously, providing constant cooling of the skin and therefore the core.

The Patch Pockets: There are pockets that are positioned on top of the blue fabric in both the base-layer, arm-sleeves, wrist-sleeves and head-band. In these pockets patches and/or ice can be placed.

The combination possibilities of applying various CoreCooling products (and use patches and/or ice) provide a cooling strategy that is fit for every training/race in any condition.

Overall: heart rate is an indicator of total stress on the body. That you have a lower heart rate with CoreCooling shows that overall stress is lower. In other words, you can have more stress and therefore specifically exert more effort. (for triathlon cycling or running harder).

If you achieve a lower heart rate and lower core temperature through cooling, you will be able to sustain your performance/intensity for longer.

At lower heart rates and lower core temperatures, your metabolism is lower. You will therefore (even if you pedal the same wattages or run the same speed) need relatively fewer carbohydrates. That makes you more efficient.

Lactate is a by-product of carbohydrate burning. So that also means that at lower heart rate and lower core temperature, you are likely to produce less lactate. And therefore a can sustain your performance longer.

If cooling allows you to keep your core temperature and heart rate lower, that results in better focus and cognitive performance. After all, you have less overall stress, so more space to think and make the right decision.

Pre and Post Cooling: CoreCooling products are versatile and can be used before, during, or after physical activities to manage core temperature effectively.

Enhanced Cooling with Ice or Water: In extreme heat, ice cubes or cold water can be used to recharge the cooling patches or directly placed in the pockets. This further extends the cooling effect, ensuring consistent temperature regulation during prolonged activities.

Double Layer Strategy: For longer-lasting cooling, place two patches on top of each other, with the blue patch in contact with the blue fabric and the orange patch on top. This keeps the cooling effect active for longer.

Using Ice: In races with high temperatures, place ice cubes directly into the pockets or on top of the patches for extended cooling. In the head-band, ice cubes can also be spread across the width to cool the forehead and temples.

Maintaining Blue Fabric: Keep the blue fabric moist for optimal evaporation cooling and easy patch insertion. If the fabric dries and becomes stiff, simply soak it in water to restore flexibility.

Patch Recharging: The patches are reusable and can be "recharged" in the freezer or with an orange patch on top of a blue one (this recharges the blue patch). Be sure to recharge once the patches turn transparent.

Disposal During Races: Although durable for long-term use, if patches need to be discarded during a race, use a T-bag or arrange for someone to collect them at designated points to reduce waste.
