Product Customer Reviews

So comfortable, warm, light...I washed an rewashed them on my ski trip as I didn't want to wear anything else!
Great baselayer used for skiing. Only negative easy to pul outs by velcro
These are great but I would recommend sizing up. I am usually a Medium but got the Large and I'm so glad I did.
Very comfortable and kept us warm during full trip of ours. Excellent product for temperature like -15 also
Warmth wise I felt it lacks a point otherwise it's good and comfortable. You definitely have to layer it up as it isn't like a warmer.
Excellent quality fabric and fitting.
Can't say anything more. It's the best thermal, skin fit, warm, cozy and love it's fabric.
Amazing service and support.
too expensive !
It was bought as a part of a set for my daughter, keeps her warm and with a good fit.
velmi pohodlné
Pohodlné, jen jako vždy moc pevné v pase. Ale to je asi u všeho :-(
jsem s výrobkem a vůbec se vším všudy od A až do Z spokojená. Libuška
Jako spodni vrstva perfektni, jen by mohly mit sirsi gumu v pase :)
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
Composition
Main fabric: 97.0% Polyamide, 3.0% Elastane
What type of fit is the bl 580 i-soft ski base layer?
The BL 580 I-Soft thermal base layer comes in a SLIM fit. They stop below the knee to avoid overlapping layers (socks + base layer) creating folds in the ski boot, which may affect your comfort. They are like a second skin that hugs the body, which reduces rubbing and improves moisture wicking.
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 fibre 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 increases the performance of the fabric through different benefits: soft, feeling of warmth and comfort for the skin. It increases the performance of the clothing thanks to better thermoregulation, damp absorption and thermal insulation. To achieve this softness, the base layer is brushed.
What is i-band technology?
I-Band technology is an innovation on the waistband of the I-Soft top and bottom base layers. It enables the fabric to always be positioned properly so that it does not ride up or fall down when skiing.
Technical structure of the product
Thanks to its intelligent body mapping and brushed polyamide fibre created from I-SOFT technology, this second skin will ensure you feel a warmth that is distributed evenly over the whole body.
