Product description
The Thermo Flex combines cold, heat, and contrast therapy in one portable device. Instead of juggling ice packs and heat pads separately, you choose between three cold levels (15 °C, 10 °C, 5 °C) and three heat levels (47 °C, 42 °C, 38 °C) at the press of a button – wireless, compact, and ready to go.
After a workout, with a mild strain, swollen joints, or tight muscles: the Thermo Flex is right there when you need it. Use the included strap to secure it hands-free to your knee, shoulder, back, or calf – and keep moving while it works.
Targeted hot & cold therapy at home, in the studio, or on the court – no appointment, no power outlet, no compromises.
Cold can help reduce swelling and the feeling of overworked muscles; heat supports circulation and eases tension. With the contrast function you combine both in one session – perfect for a consistent recovery routine.
It's super easy to use: put it on, pick your mode and level, go. The 3200 mAh battery gives you plenty of runtime on the go – so no little ache slows your day down anymore.
Can I cool and heat with one device?
Yes. The Thermo Flex offers three cold levels and three heat levels – switch with a button press and combine both in a contrast application.
How do I attach the device hands-free?
Using the included strap, you fix the Thermo Flex to your knee, shoulder, calf, or back – keeping your hands completely free.
Is there a return option?
Yes. You have a 30-day return right from receipt: within the first 14 days you can withdraw without giving a reason (statutory right of withdrawal). From day 15 to 30 we voluntarily take the item back if it is defective, was delivered by mistake or differs significantly from the description – complete with all accessories and with photo/video evidence.

Recovery doesn't have to be expensive – with the Thermo Flex
Let's be honest: if you book a studio session after every hard workout or for every tight muscle, you'll quickly rack up bills for massage appointments or recovery sessions. We think targeted hot-&-cold applications should be within reach at any time – for athletes, teams, and anyone who doesn't want to pause over something minor.

FAQ and useful information
When is cold a good fit and when is heat?
Cold is mostly used right after exercise, when muscles feel warm and worked – it leaves a pleasantly fresh feeling. Heat is better suited for tension and stiff muscles, as it stimulates blood flow.
What is a contrast application?
A contrast application alternates deliberately between heat and cold. Many athletes use this switch to combine the benefits of both in one routine.
How long should a session last?
A session lasts up to 15 minutes, then the Thermo Flex switches off automatically. In alternating mode it switches between cold and heat every 3 minutes – listen to how your body feels.
Who benefits from portable hot & cold devices?
Mainly athletes, clubs and active people who want to use cold and heat right after training or on the go – but also anyone with tense muscles in everyday life.
What should you look for when buying?
Key features are multiple adjustable temperature levels, hands-free attachment, wireless battery operation and a compact format for on the go.
When should you avoid heat or cold applications?
With certain pre-existing conditions, open wounds or sensory disorders, you should consult a doctor first. When in doubt, always check with a professional.
Can I return the Thermo Flex?
Yes. You have a 30-day return right from receipt: within the first 14 days you can withdraw without giving a reason (statutory right of withdrawal). From day 15 to 30 we voluntarily take the item back if it is defective, was delivered by mistake or differs significantly from the description – complete with all accessories and with photo/video evidence.
