Thermal underwear set Viking Sigrid bamboo viscose

Thermal underwear set Viking Sigrid bamboo viscose seamless high-waist base layer

Thermal underwear set Viking Sigrid is a women’s thermo set designed as a close-fitting base layer for cold-weather use in skiing, hiking, and multisport training. The bamboo viscose blend (79% bamboo fiber, 16% polyamide, 5% elastane) with 220 gsm fabric weight supports moisture wicking, breathability, and fast drying for stable comfort during movement. Seamless construction helps reduce chafing, while the high-waist leggings improve fit stability and support under shells, ski pants, or trekking trousers. The BAMBOO VISCOSE concept focuses on a soft, breathable fiber base that manages moisture efficiently and works well for sensitive skin, supported by antibacterial, odor-inhibiting, and anti-allergic finishing.

Features

• ➤ High-waist leggings: Increased waistband height supports fit stability and secure layering during movement.
• ➤ Bamboo viscose blend: 79% bamboo fiber with polyamide and elastane balances breathability, moisture management, and stretch.
• ➤ Seamless technology: Smooth construction helps reduce friction and chafing during long wear.
• ➤ Moisture wicking + fast drying: Fabric is designed to move moisture away from the skin and dry quickly after exertion.
• ➤ Antibacterial, odor-inhibiting finish: Helps maintain freshness during repeated use and active sessions.
• ➤ Fabric weight: 220 gsm material supports cold-season insulation as a functional first layer.

Use this thermal underwear set as the first layer under insulated or shell clothing for alpine skiing, XC skiing, touring, and winter hiking on exposed terrain. The seamless build works well for long days with a backpack, and the stretch fit supports active movement on steep ascents and descents. For a practical reference point: winter trekking in the Alps is exactly the kind of cold, variable environment where a stable base layer makes temperature management easier. It also fits everyday wear in cold weather when you want low-bulk warmth under casual clothing.
