BUILT FOR THE MOMENT BETWEEN EFFORTS.

A temperature regulating tool you hold in your palms, built for the rest between repeated efforts

DELIVERY JUNE 2026. Cancel anytime before shipment.

RESERVE KYLA PERFORMANCE™

01 / THE MOMENT

BETWEEN SETS. BETWEEN INTERVALS. BETWEEN ROUNDS.

The space where heat builds, output starts to drop, and the next effort is being shaped before it begins.

Most athletes treat this moment as waiting. KYLA treats it as work.

02 / ATHLETES

IN TRAINING. IN COMPETITION.

A selection of athletes currently testing KYLA in pre-launch.

Pelayo Menendez Fernandez

HYROX·Elite 15 Athlete and Performance Coach

"After only 3 weeks using KYLA, I've already noticed several significant positive changes in my training. Better repeatability between intervals, more stable output, and faster recovery between hard efforts."

Pelayo Menendez Fernandez

RECOVERY

Up to 50% deeper heart-rate recovery between efforts

Measured across our testing pool. Pelayo's three-week in-training observation contributed to qualitative pattern confirmation.

Kenny Steger

HYROX·Swedish Record Holder

"The feeling is unusual. In the higher intensity sessions I can increase my output toward the end rather than fade. That is the part that surprised me."

Kenny Steger

OUTPUT

5 to 12% sustainable output gain

Modeled across our testing pool, including Kenny's higher-intensity HYROX sessions.

Jeppe Risvig

Running·1500m in 3:41 & 10k in 29:30

"I ran quicker than usual with measurably lower lactate. Heart rate was the same. The feeling was different - like the same work cost less. I do this session three times a week, so I trust the comparison."

Jeppe Risvig

FATIGUE

Up to 25% lower blood lactate at matched pace

Measured in Jeppe's treadmill threshold session, against his three-times-weekly baseline.

03 / THE MECHANISM

OUTPUT DROPS BEFORE YOU DO.

Across repeated efforts, internal temperature rises and the body shifts capacity from output to heat management. KYLA is built to support that regulation between efforts, so the next one can hold its shape.

Heart rate recovery degrades across an unaided session. KYLA holds it consistent. View methodology

THE SCIENCE BEHIND IT

04 / THE TOOL

ENGINEERED FOR THE TIME BETWEEN EFFORTS.

A temperature regulating tool, designed for repeated efforts. Built for high heat transfer between sets and intervals. Made to be carried, used, and trusted across an entire session.

  • UP TO 9 HOURS COLD. 35-40 MINUTES ACTIVE PER PRE-COOL
  • NO BATTERIES, NO ELECTRONICS, NO SETUP
  • Used between sets, intervals, and rounds

Delivery June 2026. Cancel anytime before shipment.

05 / THE DIFFERENCE

HEAT TRANSFER. NOT TEMPERATURE.

Most cold objects stay cold on the surface but never move heat from the body fast enough to matter. KYLA is engineered around the rate of transfer. The internal construction is built to draw heat continuously across an entire session, not just feel cold against the skin.

06 / THE SCIENCE

BUILT ON PUBLISHED RESEARCH.

KYLA is built on established thermoregulation science. The materials, internal construction, and use protocol are designed to support how the body naturally manages heat under load.

  • BASED ON ESTABLISHED THERMOREGULATION RESEARCH
  • DESIGNED AROUND THE BODY'S NATURAL HEAT MANAGEMENT
  • SUPPORTED BY PUBLISHED SPORTS SCIENCE

Frequently asked questions

Quick answers to the most common questions about KYLA Performance. For more, see the full FAQ.

How does KYLA Performance actually work?

During training, heat builds in your working muscles and core. As internal temperature rises, your body shifts capacity from output to heat management, and performance starts to drop before you feel it.

KYLA Performance is used during rest periods between efforts. Held in the palm, it draws heat out of the body through the palms, which contain a dense network of specialised vessels designed specifically for releasing heat. Core temperature stays steadier across the session. Output holds longer across repeated efforts.

Who is KYLA Performance for?

Athletes who train with repeated high-intensity efforts. HYROX, strength training, intervals, functional fitness, running, cycling, rowing. Anywhere heat builds across a session and rest periods exist between efforts. The harder the session, the more measurable the effect.

How do I use it during training?

Pre-cool KYLA Performance in your refrigerator overnight, or for a minimum of three hours before training. Bring it to the gym in the dust bag. Hold one in each palm between efforts: between sets, between intervals, between rounds. Most athletes feel an effect within thirty seconds.

Is this just holding something cold?

No. Heat transfer depends on the conductivity of the material in contact with your skin, not temperature alone. KYLA Performance is engineered for high heat transfer rate, holding a temperature between 13 and 15°C, the zone where heat extraction is most efficient. The goal is not maximum cold. It is maximum heat transfer.

When will my order ship?

Delivery is June 2026. The first production run is limited to 1,500 units, with 500 reserved for founding athletes. Cancel anytime before shipment for a full refund.

What is the warranty?

KYLA Performance is covered by a two-year warranty against manufacturing faults. If something stops working as it should, contact support and we will replace it.
