odpovidajici vyrobek

Kalhoty jsou funkcni, z prijemneho materialu. Rekla bych, ze ale maji bud prilis nizky rozkrok, nebo ultra vysoka zada. Kdyz si je oblecu poradne, mam vrchni lem az pod prsy (merim 165 cm, uvedomuji si, ze to muze zapricinit mensi postava). Ale zase se urcite nestane, ze byste mely hola zada.

Additional Product Information


Main fabric

  • 97% Polyamide, 100% of the thread is dope dyed
  • 3% Spandex

What is the fit of the i-soft base layer?

The I-Soft base layer comes in slim fit. It stops below the knee to avoid creating too many layers (socks + base layer), which can create uncomfortable folds in ski boots. It is a 2nd skin with a slim fit that reduces friction.

What are the benefits of polyamide?

Polyamide has the highest strength of all textile raw materials (even when wet) and is very stretchy. This breathable fiber manages moisture very well and provides good temperature regulation. These specially textured super-soft yarns give fabrics a silky, natural feel. Ideal for tight, seamless clothing.

What is i-soft technology?

I-Soft technology enhances the fabric's performance, providing a variety of benefits: softness, warmth, and next-to-skin comfort. It also enhances garment performance, providing better heat regulation, humidity absorption, and thermal insulation. To achieve this softness, the base layer is brushed.

What is i-band technology?

I-Band technology is an innovative design used around the waist of the I-Soft top and bottom base layers. It helps keep the garment in place so that it doesn't ride up or fall down when skiing.

Technical structure of the product

Thanks to its intelligent bodymapping and brushed polyamide fiber created from I-Soft technology, this 2nd skin will ensure you feel a warmth that is distributed evenly over the whole body.
