Sehr gute Tight für den Sport

Für meinen Sohn war ich auf der Suche nach einer neuen Tight, die er beim Rennradtraining bei kalten Tagen anziehen kann. Zu erst war ich mir nicht sicher, ob diese Tight, die eigentlich fürs Laufen ist auch dafür geeignet wäre. Aber mittlerweile hatte er sie oft genug auf dem Rad an und trägt sie auch ziemlich gerne. Die Tight sitzt sehr eng anliegend an seinen Beinen und wirft keine unangenehmen Falten, weswegen er sie auch bei langen Touren trägt. Die Reißverschlüsse unten an den Knöcheln findet er cool, weil er die Tight so viel leichter anziehen kann und sie danach auch bis zu den Knöcheln hauteng abschließt. Am Oberschenkel befindet sich noch eine Tasche mit Reißverschluss. Auf dem Rad kann er diese nicht nutzen, da er über dieser Tight noch seine Radlerhose mit Polsterung anzieht. Aber auch für den Sport in der Schule packe ich ihm diese Tight ein. Dort kann er die praktische Tasche benutzen. Alles in allem eine sehr gute Sport-Tight. Wir können sie klar empfehlen!

Super für KanuPolo bei Regenwetter

Hose hielt sehr warm. Innenseite angeraut und angenehm zu tragen

Additional Product Information


Main fabric: 91.0% Polyethylene Terephtalate, 9.0% Spandex

How kids cope with the cold:

Following a study conducted by our research laboratory (SportsLab), we have scientific proof that kids are more sensitive to the cold than adults! Unlike adults, who tend to feel the cold gradually, the feeling of discomfort occurs suddenly for most kids.For 1-day competitions or training sessions below 23°F, we recommend wearing a pair of pants over the tights, which can be removed when working out.

Tights made with plastic bottles

Polyester is made from oil-based chemical derivatives. The CO2 emissions of this material are significant, and resources are used up in the production process. It is important to provide a solution to the environmental concerns of sports users through innovation in industrial processes, recycling, and the circular economy. That's why we have chosen to make this product out of recycled polyester made from plastic bottles.

Storage instructions
