01
Product and usage
How do I use KYLA Performance during training?Chill it five hours, then one in each palm between efforts.
Chill the pair for at least five hours, bring it in the carry bag, and hold one handle in each palm between sets, intervals or rounds. Use the rest you already take. From 30 seconds it counts. Between sets, hold 60 to 90 seconds. In longer breaks, keep holding as long as the break lasts.
How do I prepare it before training?Five hours in the fridge, overnight is better. The freezer is faster but overshoots, so let the pair rest at room temperature for an hour and a half before you use it.
The freezer is faster but it overshoots, so let the pair rest at room temperature for an hour and a half before you use it. Too cold is not better. The carry bag holds the chill, so keep the pair in it. Bagged, a pair stays cold 10+ hours at room temperature, before you start using it, so there is no rush and no fridge needed at the gym.
How long does a single pre-cool last during a session?30 to 35 minutes of contact in total, spread across the rests.
The minutes count as time in your hand, added up across the session, not as a countdown from the moment you take it out. That is enough to cover the rests in a full session.
We could have made it last longer. It would have pulled less heat. We chose heat.
Can I just hold something frozen instead?No. Too cold narrows the vessels in your palm, and a frozen object only takes heat where it touches.
No, and for two reasons. Something very cold makes the vessels in your palm narrow, so less blood reaches the surface and less heat leaves. And a frozen object takes heat only where your palm touches it, and that thin layer warms in seconds. Inside KYLA the heat spreads into ten times more cold surface than your palm touches, so it keeps leaving. The surface sits around 14 °C. The goal is not maximum cold. It is maximum heat out.
Can everyone use KYLA Performance? Is it safe?Most people, yes. Check first if circulation or hand sensitivity is a concern.
KYLA Performance works with the body’s natural heat release system. 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.

Science and effect
How does KYLA Performance actually work?You hold it in the rests you already take, and heat leaves through your palms.
Heat builds in your muscles and core while you train, and your output drops before you feel tired. Your palms are the fastest heat exit you have. Hold a cold surface there in the rests, and heat leaves through the blood.

Who is KYLA Performance for?If your session has hard efforts with rests between them, it is for you.
If it does not, keep reading.
The sport does not decide it. The shape of the session does. If you work hard, stop, and work hard again, there is heat to move and a rest to move it in.
If your session runs without a break, there is less for it to do while you train. Two things still work. Hold it before you start, so you begin cooler. Hold it in any break you do get, however few there are. If you never have a hand free during a session, this is not for you, and we would rather say that than sell you a pair.
When will I notice an effect?You notice it in the first rests. Judge it on the whole session.
Whether that turns into more work is a session-level question, so judge it over a full session. The difference shows up in the efforts you usually grind or cut short. Across a session we measure deeper heart-rate recovery between efforts, lower perceived effort at the same workload, and output holding more consistently. See Our testing so far.
