4F is a Polish sportswear house built by Igor Klaja and now worn by Olympic teams across Europe. What started as a specialist ski-shop brand has grown into technical outerwear and layering that actually copes with cold, wet mountain days — not just looking the part on the gondola.
At Welcome Board Store we keep a focused 4F snow range — base layers, ski pants and a snow jacket — ready to ship from our Australian warehouse in Mornington, VIC.
Thermals & layers
Brushed, thermoactive fleece next to the skin is how 4F keeps you warm without a bulky stack of layers:
- Tracy Womens Thermal Fleece Underwear Top — women’s-specific fleece base layer for under a shell.
- Stan Mens Thermoactive Fleece Underwear Top — men’s matching top with a close, active fit.
- Men’s brushed thermoactive underwear (top) — black, no-nonsense mid-weight thermal.
- Women’s Thermoactive Fleece Underwear (TOP) — the women’s black fleece thermal for resort and touring days.
Ski pants & jackets
- Janet Womens Ski Pants and Pro Ellen Womens Ski Pants — women’s ski pants cut for movement, not just standing in a lift line.
- Evan Mens Pro Ski Pants and Josh Mens Ski Pants — men’s ski pants with a proper mountain cut.
- Charlie Mens Snow Jacket — a technical 4F snow jacket to pair with the pants above.
