Ich habe die Thermounterwäsche für den Winter und Outdoor-Aktivitäten gekauft und bin wirklich sehr zufrieden. Das Material fühlt sich angenehm auf der Haut an und wirkt hochwertig verarbeitet. Tragekomfort & Passform: Die Unterwäsche sitzt gut am Körper, ohne einzuengen, und bleibt auch bei längerer Nutzung bequem. Sie lässt sich problemlos unter normaler Kleidung oder Skibekleidung tragen. Wärme & Funktion: Gerade bei kalten Temperaturen merkt man die gute Wärmeisolierung deutlich. Gleichzeitig bleibt das Material atmungsaktiv, sodass man sich auch bei Bewegung wohl fühlt. Was mir besonders gefällt: sehr angenehmes Material gute Wärmeleistung bequemer Sitz ideal für Winter und Outdoor Fazit: Für mich eine richtig gute Thermounterwäsche, die ihren Zweck perfekt erfüllt. Würde ich jederzeit wieder kaufen – klare 5 Sterne.

Sie hält warm wen es nicht allzu kalt ist, ca bis 3-5 Grad beim Fahrradfahren. Wenn es kälter ist 2 Stück übereinander ziehen 🫣😂
