Your first session.

Cool, calm, and after a minute, almost unremarkable. That is by design. The rule is simple: if it feels good, it is doing its job. You are helping your body get rid of heat, and you may notice the signs of that during the rest. Breathing settles. Heart rate comes down. The head clears a little before the next effort. Over a whole session, the point is output that holds steadier into your last sets.

Cold should never be the sensation. If KYLA feels too cold, it is too cold: rinse it under tap water for about 30 seconds and it is back in its working range. If your palms ever feel numb, stop, let the pair warm up, and start again later.

There is no battery. You charge KYLA with cold.

In the fridge: 7+ hours is the ideal charge, and overnight is even better. Simplest is to make the fridge its home: when you are not training with KYLA, it lives there, always charged. Stand the pair upright, not in the door, and preferably toward the back and lower down, where the temperature is coldest and most stable.

In the freezer: it is the fast option, but it overshoots. Too cold is not better. It is uncomfortable, and it makes the vessels in your palm contract, which slows the heat leaving your body. If you use the freezer, take the pair out at least an hour before you train, or bring it back faster with the 30-second rinse under the tap.

In the pouch: once chilled, the pair stays ready for 7 hours or more. A morning chill covers an evening session.

Both, usually. One handle in each palm is the standard between efforts. But the second handle does not double the effect: on its own, each handle gives its full effect, and using two at once adds about 70 percent on top of one.

That is worth knowing for really long sessions: use one handle at a time and you stretch the charge, so the cooling lasts deep into the day.

Clean it with ordinary soap and water, then dry it. That is the whole routine.

When it is not in the fridge, store it at normal room temperature. Keep it away from long spells in direct sun or a hot car. Absorbing your heat is its job. Fighting the sun all day is not.

Not gently. KYLA is not fragile. It is built for gym floors, chalk, dropped bags, and being passed between hands. Scratches and marks change nothing about how it works. The only thing that matters is the seal: as long as it does not leak, you are all good. If a unit ever leaks or breaks, reach out to us.

KYLA works with the body's natural heat release. Most people can use it without any issues. If you have a condition that affects circulation or sensitivity in your hands, check with a healthcare professional before use. Avoid use on injured, numb, or broken skin.
