Indispensable para este curso

Dadas las nuevas condiciones en las que van a dar clase nuestros hijos, esta camiseta es mas que recomendable para evitar pasar frio en clase, pues este invierno van a estar con las puertas y ventanas abiertas. Es ideal, ligera y suave. Mis chicos encantados con ella. 100% recomendable.

Additional Product Information


Main fabric

  • 96% Polyamide
  • 4% Spandex

What type of fit is the i-soft 580 base layer ski top base layer?

The I-Soft 580 Base Layer Ski Top comes in slim fit. It is 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 very 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.

How should kids dress to ensure they keep warm on the ski slopes?

To keep warm and dry, just apply the 3 technical layers rule: Layer 1 or 2nd skin, to stay dry. Layer 2 or an insulating layer, to keep the heat in. Layer 3 or a protective layer, to protect against bad weather.

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.)



Product testing

All Wedze products are created, designed, and developed in the Mont Blanc Valley. They are then tested under the same conditions as you would experience in real-life use (snow, cold, powder snow, etc.). The design teams ensure that the program for which the product has been designed and developed matches perfectly with its use in the field.
