Thermo Flex

The Thermo Flex is a portable recovery device that combines cold, heat and contrast in one compact unit. You strap it hands-free directly to the area you want – wireless, ready to go, no ice packs or heat pads needed.

It's built for targeted recovery exactly where you need it: knee, shoulder, neck, back or calf. Whether after training, for a cool refresh or to loosen tight muscles – your hot-&-cold routine is always within reach.

Three cold levels (down to 5 °C) and three heat levels (up to 42 °C) switch at the press of a button. One device replaces what used to need ice packs, heat cushions and a power socket.

Cold cools pleasantly and has a calming effect on hard-worked muscles – ideal for a fresh, light feeling after tough sessions.

Heat stimulates circulation and makes tight, stiff muscles supple again.

With contrast you switch deliberately between warm and cold. This alternation feels invigorating, stimulates circulation and is a fixed part of many athletes' recovery routine. The Thermo Flex makes exactly this switch possible at the press of a button, with three levels each for cold and heat.

Heat (3 levels up to 42 °C) works best before exercise and for tension: it loosens muscles and stimulates circulation.

Cold (3 levels down to 5 °C) is ideal after intense exercise or whenever you want a quick cool-down: it has a calming effect and leaves you feeling refreshed and light.

Contrast (alternating warm and cold) is great for recovery when you want to combine the benefits of both in one routine. On easier days, gentle heat is often all you need.

Thanks to the adjustable strap, the Thermo Flex fits many body areas. Typical use cases:

• Knee: after running and jumping sessions
• Shoulder & neck: for tension after long periods of sitting or training
• Back: upper and lower back for stiff muscles
• Calf & thigh: for tired legs

Target exactly the area that needs attention – hands-free and without holding anything in place.

Using the included adjustable strap, you fix the Thermo Flex directly to your knee, shoulder, calf or back. The strap stays secure without cutting in – so your hands stay free.

That means you can keep moving, stretch or simply relax while the session runs. No holding, no cable, no power socket.

Strap the device onto the target muscle area and select your level. A session lasts up to 15 minutes, then the device switches off automatically. Start at a moderate level and adjust intensity to how it feels.

Before exercise:

Use heat to warm up and activate your muscles.

After exercise:

Use cold or contrast to calm tired muscles and support recovery. With contrast, alternate between warm and cold several times.

Yes, the Thermo Flex is fully wireless and runs on a built-in 3200 mAh battery. It charges conveniently via the included cable and is ready for multiple sessions.

So you're not tied to a socket – use it on the pitch, in the studio or on the go. At roughly 149 × 76 × 50 mm, it fits in any sports bag.

Anyone who doesn't want to stop for every little niggle: athletes, teams and active people who want to take their recovery into their own hands – plus anyone with tight muscles from everyday life.

Because you control intensity and temperature yourself, the Thermo Flex works equally well for intense post-competition recovery and a relaxed evening routine. You decide what your body needs right now.

Heat and cold applications should not be used if there are medical reasons against it. You can use the Thermo Flex on muscles, joints and the neck, but never apply it directly to the spine, the head or to injured areas. If you're unsure or have a pre-existing condition, please check with your doctor first.

Do not use with:

• acute injuries, fresh bruises, sprains or fractures
• open, irritated or infected skin
• cold intolerance (e.g. Raynaud's syndrome, cold urticaria) – applies to the cold function
• circulatory disorders, thrombosis or known tendency to thrombosis
• acute inflammation, fever or infections
• malignant tumours in the area of application

Consult a doctor first if you have:

• reduced sensitivity to heat, cold or pain (e.g. diabetes with neuropathy)

• a pacemaker or other implanted devices
• pregnancy
• post-operative conditions or joint replacements
