Additional information

Electronic coaching
This tank top has built-in electrodes to measure your heart rate. User guide: 1. Place the sensor on the 2 press buttons on the front of the tank top. 2. Moisten the electrodes inside the product to get the best reception of the heart rate signal. 3. Wait for your watch or your phone to receive your heart rate.
This tank top is compatible with all sensors from the Géonaute, Kalenji, Polar and Garmin brands that have press buttons. Check the attachment distance from the 2 press buttons. This distance is 4.5cm on the T-shirt.
Reduced chafing
Wear this tank top close to the body like a second skin to reduce movement of the product as much as possible and thus prevent chafing. It is also designed with "seamless" technology which means the torso is seam-free so any chafing can be avoided.
Perspiration wicking
This tank top is designed to stay dry while you're running. Your perspiration is absorbed and dries quickly.

    Ich hoffe das Shirt ird niemals ein Auslaufmodell

    Es ist das einzige Shirt mit Cardio Funktion auf dem Markt es passt zu sehr vielen Bluetooth Frequenzmessern wir z.B. dem Polar H7 oder dem Polar H10 ich nutze beide. Auch passt der von Runtastic sowie der günstigste von Kalenji selbst hervorragend! Das Shirt ist ein Komoressionshirt und liegt hauteng und sehr angenehm an und ist suuuuuper geschnitten! Eine super Kaufempfehlung! Mann macht nichts falsch!

    Super Produkt

    Funktioniert super!
    Ich habe beide Varianten des Shirts, allerdings ist mir auch die Ärmellose Varriante bei Sonnenschein zu warm. Gut wäre noch eine Variante (vieleicht auch in weiß) als Achselshirt für heisse Tage.

    Mich hat immer der Brustgurt gestört . Mit dem Shirt ist alles top. Das Shirt ist mit meinem Garmin Brustgurt kompatibel. Der Gurt muss bei einen neuen Shirt aber gut nass gemacht werden. Umso öfter es gewaschen wird umso besser passt der Gurt am Körper, umso besser die Messung.

    Per chi non sopporta la fascia cardio!

    Ho regalato questa maglia di intimo al mio compagno per la corsa. Lui non sopporta la fascia cardio perché gli crea irritazione. Con questa ha risolto il problema e funziona benissimo!
