The Arctic Heat Ice Vest for Running: Pre-Cool, Perform, Recover

Running in Australian summer heat is one of the hardest things you can ask your body to do. Core temperature rises quickly, blood gets diverted from your muscles to your skin, and performance drops fast. The Arctic Heat ice vest gives runners a thermal buffer before they start, helping them run harder, longer, and more safely in hot conditions.

Why does heat hurt running performance so much?

Running generates more heat per kilogram of bodyweight than almost any other sport. When your core temperature climbs above 38 to 39 degrees Celsius, your brain begins to reduce your running pace as a protective mechanism. Pre-cooling with an ice vest before you run delays that temperature rise. Studies on distance runners show pre-cooling can improve 5km time trial performance by 1 to 2 percent and significantly reduce perceived effort in hot conditions.

How do runners use the Arctic Heat vest?

• Pre-run (most important): Wear the vest for 30 to 45 minutes before your race or hard session. Remove it just before you start your effort.
• During recovery between reps: For track sessions, put the vest back on during recovery between hard efforts.
• Post-run recovery: Wearing the vest immediately after a hot run brings core temperature down faster and supports quicker recovery.

Is the Arctic Heat vest good for marathon running?

Yes, particularly at Australian marathons in warm conditions. In the 60 minutes before your wave starts, put the vest on during your warm-up. Keep it on at the start line for as long as possible. Hand it to a supporter in the final 5 minutes before the gun.

Does the vest work in Queensland and tropical heat?

Yes. The Arctic Heat ice vest uses crystal gel panels that cool through direct conduction — not evaporation or airflow. It works just as well in high humidity as in dry heat, making it the most reliable pre-cooling option for Australian runners regardless of location.

The Arctic Heat ice vest is also popular with US-based runners and is available through Arctic Heat USA.

Frequently asked questions

How long before a run should I put on the ice vest?

30 to 45 minutes before your race start or hard session.

Will the ice vest make me feel too cold before a run?

You may feel cold initially. This is normal and desirable. Your body temperature will rise quickly once you begin running.

Can I use the ice vest for parkrun?

Absolutely. Wearing an ice vest in the 30 minutes before your parkrun start is one of the easiest ways to improve your time on a hot day.

What size ice vest should a runner choose?

Measure around your chest at its widest point. Choose the smaller size if between sizes: XXS 80cm, XS 85cm, S 90cm, M 95cm, L 100cm, XL 105cm, 2XL 110cm.
