Bolt bundle

We created a cutting edge recovery tool designed to help regulate core body temperature using hand-held, precision-machined aluminum "bolts." It provides rapid cooling during or after intense physical activity.

By holding then anodized aluminum bolts in your hands, heat from your body is transferred to the cooler surface of the bolt. This helps cool the blood circulating through your palms, which can assist in reducing overall body temperature and fatigue.

Yes. Our concept is inspired by peer-reviewed research on palm cooling and core temperature regulation, a method increasingly used by elite athletes, military units, and performance trainers.

Athletes, fitness enthusiasts, physical workers, people with heat sensitivity, and anyone seeking improved stamina, reduced fatigue, and faster recovery.

Hold one bolt in each hand during breaks, between sets, or post-exercise. For best results, use for 1–2 minutes or until your body feels rebalanced.

Simply wipe them down with a damp cloth and mild soap if needed. Avoid harsh chemicals or abrasive materials.

Yes, they are lightweight and designed for intermittent use during or between exercises, especially when resting or rehydrating.

Yes, Bolt Cooling is completely passive and safe. It contains no electronics, liquids, or chemicals.

We ship worldwide. Shipping costs and delivery times are calculated at checkout.

Yes, we offer a 1-year limited warranty covering manufacturing defects.

Yes, Bolt has a proprietary design inspired by cutting-edge thermal performance research. The patent is pending. Each unit is precision-machined and part of a limited production run.
