Product Customer Reviews

Top Qualität
Alles gut
Retiene el sudor y es muy conformtable
Muy cómodo, no se arruga
Lo compre para mi hijo y va muy cómodo.
Buena relación calidad/precio
Son cómodas, se adapta perfectamente al cuerpo y mantienen el calor corporal
Lo que realmente se busca a la hora de ponerlo debajo de otra prenda.
Bon rapport qualité prix
Ce vêtement n'est pas utilisé pour le ski mais dans le cadre des entraînements de kayak slalom. Les enfants qui le portent en sont ravis. C'est agréable à porter et leur garanti une douce chaleur. Il resiste bien aux fréquents lavages.
Super sous vêtement mais taille petit
nickel
Il est bien, mais mon fils a préféré les collants et au final je rachèterai les collants pour faire du ski et pas ce sous-vetement pour cet age (9ans). Par contre, tres bien pour sortir dehors ou faire du sport autre.
Tien chaud rien a redire a voire dans le temps
qualité prix excellent
Additional Product Information
Composition
Main fabric
- 96% Polyamide
- 4% Spandex
What type of fit does the i-soft 580 base layer ski pants base layer have?
The I-Soft 580 Base Layer Ski Pants comes in a slim fit. They stop below the knee to avoid overlapping layers (socks and underwear) creating folds in the ski boot, which may affect kids' comfort. The asymmetric waistband gives an excellent fit around the waist. They are like a 2nd skin that hugs the body, which limits rubbing.
What are the benefits of polyamide?
Polyamide has the highest resistance of all textile raw materials (even when damp) and is very stretchy. This breathable fiber gives extremely good moisture management, reducing odors thanks to its natural properties as well as good temperature regulation. These specially textured, super-soft yarns give fabrics a silky, natural feel. Ideal for tight, seamless clothing.
Technical structure of the product
With its intelligent body mapping and brushed polyamide fiber created from I-SOFT technology, this 2nd skin will ensure kids feel warmth that is distributed evenly over their whole body.
A product-specific environmental rating
The environmental impact of the product is calculated over its entire lifecycle and using various indicators. An overall ABCDE score is given to help you easily identify products with the best environmental performance by comparing products of the same type (T-shirts, pants, backpacks, etc.)
