Alpinus Idre Women's Thermal Underwear Set (SI35154) – Black

The perfect foundation for year-round active comfort. The Alpinus Idre Set is a premium two-piece women's thermoactive base layer, including a long-sleeve functional shirt and matching full-length leggings. Engineered for light to moderate outdoor activities, this set keeps your body at its optimal temperature by preventing both chilling and overheating. Part of the Tactical / Active line, it is crafted using recycled polyamide fibers, making it a highly reliable and eco-conscious choice for any season. 

Key Features & Benefits

  • Advanced Fiber Blend: Combines 70% recycled polyamide, 23% polyester, and 7% elastane to deliver immediate moisture absorption and rapid outer evaporation.
  • Quick Dry Technology: High-performance synthetic yarns actively wick sweat away from the skin, drastically reducing material drying time.
  • Targeted Vent Areas: Strategically placed structural mesh panels improve multi-directional air circulation in high-perspiration zones.
  • Seamless & Flatlock Finish: Seamless torso engineering and smooth flat seams minimize friction, eliminating the risk of chafing and skin irritation.
  • Anti-Static Fibers: Specially treated knit fabric prevents the static cling common in synthetic clothing, enhancing all-day wearability.
  • Unrestricted 4-Way Stretch: Highly elastic construction adapts smoothly to the female anatomy like a second skin without restricting movement. 

Hiking & Outdoor Recommendations

The Alpinus Idre set acts as a highly versatile base layer across different weather conditions:
  • Autumn & Spring Mountain Trekking: Worn as a standalone layer on the trail, it provides adequate wind protection and thermal balance when traversing exposed ridges.
  • Recreational Alpine & Cross-Country Skiing: Serves as the ultimate moisture-wicking foundation layer under ski pants and insulated hardshell jackets, preventing a damp chill during lift rides.
  • Winter Trail Running & Nordic Walking: The targeted ventilation zones excel during high-intensity cardio in cold air, keeping your core dry while the anti-static build prevents friction with mid-layers.
  • Cold-Weather Camping & Everyday Comfort: Thanks to its non-restrictive, flat-seam fit, it is exceptionally comfortable to wear as a warm pajamas layer inside a sleeping bag or discreetly under standard work jeans on freezing days.
