Why Thermals Deserve a Prime Spot in Your Winter Wardrobe

Thermals are the quiet hero of winter dressing. Here’s why they’re essential:

• Thermal knit construction and stretch fabric: Moves with your body for a flattering fit.
• Thermal blend fibres with moisture-wicking technology: Keeps you warm and dry in all weather.
• Brushed cotton inner layer and super brushed inner layers: Ultimate softness for sensitive skin.
• Flatlock seams: Reduce irritation and improve comfort during active wear.
• UPF50 fabric: Added sun protection for outdoor activities.
