Our focus: The Core

4 FIS stars and a flexible fit

The Core is Diston’s range for competitive skiers who place high demands on both protection and freedom of movement. The pants and tops feature four-way stretch and a close-fitting Racing Fit, developed to work under the race suit during both training and competition.

At Skidvalla.se, we focus on The Core with 4 FIS stars. The range is ideal for skiers who train regularly and want a high, documented level of cut resistance in a flexible garment.

Protection and rating

Understand the protection in your base layer

Why use a cut-resistant base layer?

A regular base layer is chosen primarily for warmth, moisture management, and comfort. A cut-resistant base layer also includes materials tested to withstand cutting. Diston's garments are developed to provide extra protection when the skis' steel edges come into contact with the body.

Cut protection is a supplementary form of protection and cannot guarantee that a laceration will never occur. The right size, coverage, and use are therefore important parts of the selection.

What do 4 FIS stars mean?

The FIS stars indicate the material's cut resistance according to the FIS-DITF 2021 test standard. The scale ranges from 1 to 5 stars. Four stars are the second-highest level and mean higher measured cut resistance than three stars.

The Core combines this level of protection with four-way stretch and Racing Fit. The achieved level is shown on the garment's FIS marking.

Cut resistance and abrasion resistance

In addition to cut resistance, Diston states abrasion resistance at level 4 out of 4 according to EN 388:2016 for The Core. This is the highest level in the standard's abrasion test and describes the material's resistance to wear. It is a separate property from the four FIS stars.

According to Diston, The Core garments are also certified as personal protective equipment, PPE category II, in accordance with EU Regulation 2016/425.

FIS cut-protection requirements 2026/2027

According to the FIS equipment rules for 2026/2027, cut-protection pants are mandatory at all alpine FIS competitions. The pants must provide at least 3 FIS stars of protection from the iliac crest to the top edge of the ski boot. Cut-resistant tops or race suits are strongly recommended.

The Core pants' 4 FIS-star rating is above the minimum cut-resistance requirement. Correct coverage, FIS marking, and use in accordance with the manufacturer's instructions are also required. Check the rules for your competition and season.
