Swix Polaris Baselayer Halfzip W – women’s merino base-layer top

Manufacturer’s product number: 10445-26
Colour: Jet black · 10120

Swix Polaris Baselayer Halfzip W is a women’s 100% merino wool base-layer top for cross-country skiing and winter outdoor activities. Merino helps regulate temperature as effort changes, and the half zip adds adjustment for cold-weather layering.

Worn next to the skin, it adds warmth beneath a ski jacket or midlayer. Flatlock seams reduce seam bulk, and the chin guard finishes the collar. Polaris suits skiers who value merino’s feel, particularly on easy winter outings.

Key Features

• 100% merino wool for natural temperature regulation.
• Breathable, moisture-managing material.
• Half zip for collar adjustment.
• Flatlock seams.
• Chin guard and YKK zipper.

XCSKIguru Tips

• For easy endurance skiing: Polaris is an option for long outings in freezing conditions when you generate less heat than during intervals. Choose the jacket and any midlayer according to wind chill and your own warmth needs.
• Under Triac or Horizon? With Triac Windstopper Jacket W, add a midlayer if needed. Horizon Jacket 2.0 W and Elevation Jacket W already have insulation, so I would first try them with just the base-layer top.
• Pair with Polaris Baselayer Pants W for a merino base-layer set. Upper and lower layers need not be equally warm: the chest may need another layer while the legs are comfortable with less.
• Another option for hard training: if you sweat heavily on tempo climbs or intervals, compare a lightweight synthetic top. Merino can be your choice for easy cold-weather skiing even if you use something else for harder sessions.
