Each pack includes two suits, allowing for alternating use or training with a partner.

Engineered as a portable environmental chamber, the suit accelerates the body’s heat strain index with less physical effort, helping athletes reach ideal training conditions faster. This not only supports thermal adaptation but also encourages physiological changes that can enhance endurance and performance in hot race conditions.

The material is highly durable and reusable – after each session, simply rinse the suit in the shower and hang to air dry. Sizing is based on height, and customers are encouraged to size up if unsure, as returns are not possible for hygiene reasons.

IMPORTANT WARNING

Overexposure to high temperatures can be dangerous to your health and the use of this product can lead to dehydration, heat stroke, heat exhaustion, and other heat-related illnesses, and in extreme cases, death. Please read the article on Heat Safety.

To reduce the risk of overheating and dehydration, drink plenty of water before, during and after the use of the suit. If you experience dizziness, vomiting, muscle cramps, nausea, and/or light-headedness, stop using the suit and seek emergency medical help immediately.

If you are over 65, suffer from a heart condition, high blood pressure, diabetes, respiratory condition, and/or under medical treatment, please do not use the suit without consulting a physician or a healthcare provider. Pregnant women and children (under the age of 18) should not use the suit under any circumstance.

This is not a toy. To avoid danger of suffocation, keep the suit out of reach of babies and young children.

The CORE Heat Training Suit creates a controlled, high-heat environment around your body by trapping heat and moisture. This accelerates the rise in core temperature and reduces the mechanical workload needed to achieve your desired Heat Strain Index. In short, you can trigger heat adaptations faster without needing to increase training intensity.

This approach is especially useful for athletes preparing for events in hot climates or working to build heat tolerance during cooler months. By repeatedly exposing the body to elevated internal temperatures, you can improve plasma volume, sweat response, and thermoregulation, all of which support better performance and comfort when racing in the heat.
