Technical and Thermal Base Layers for Men, Women and Children
Glisshop offers a wide selection of technical base layers and thermal underwear suitable for all types of outdoor enthusiasts: men, women and children. Whether you’re a skier, hiker, snowboarder or trail runner, these garments are engineered to follow every movement and optimise body temperature regulation.
Breathable, insulating and lightweight, base layers provide optimal comfort throughout your outing, whatever the conditions.
- Some models focus on moisture management for high-intensity pursuits.
- Thermal underwear, on the other hand, retains warmth effectively during the coldest days.
The Glisshop collection brings together a broad range of high-performance materials — merino wool, polyester, polyamide or recycled fibres — to deliver the best balance of warmth, breathability and freedom of movement.
Extreme Cold Thermal Base Layers
The first element of your ski or snowboard kit, the thermal base layer acts like a warm, discreet second skin, ensuring lasting comfort day after day. It retains body heat, wicks away perspiration and provides consistent comfort.
- Long-sleeved top and thermal leggings effectively protect both upper and lower body, even during prolonged exertion.
- These garments reduce the sensation of cold and help maintain a stable temperature throughout your outing.
A thermal garment for extreme cold acts as a true barrier against low temperatures.
Made from synthetic fibres, merino wool or a blend of both, it regulates body heat and manages perspiration without leaving you feeling damp.
The Best Brands of Technical and Thermal Base Layers
Make the most of your ski season with Glisshop and complete your ski outfit with premium garments from adidas, Bjorn Daehlie, Bula, Craft, Eivy, Falke, Gore, Icepeak, Kari Traa, Maloja, Odlo, Patagonia, Picture Organic Clothing, Protest, Rossignol, Superdry and Swix.
What Is a Technical Base Layer?
A technical base layer forms the essential foundation of any ski, trekking or outdoor outfit. Worn directly against the skin, it acts as an interface between your body and the outer layers. Its purpose: to maintain a stable temperature and efficiently wick away perspiration.
Thanks to innovative fibres, these garments are soft, breathable and quick-drying, ensuring consistent comfort even during long sessions. By regulating moisture and preventing the chill caused by sweat, the technical base layer plays a key role in both performance and comfort.
- Most models feature flatlock seams and an ergonomic construction for maximum comfort and warmth.
- These details prevent chaffing, even during repetitive movements, ensuring the first layer remains pleasant to wear all day long.
Which Material Is Best: Synthetic Fibre or Merino Wool? Comparison
The choice of a thermal base layer depends on the activity and weather conditions.
- Synthetic fibres provide lightness, breathability and quick drying. They are ideal for hiking apparel and medium- to high-intensity sports.
- Merino wool, on the other hand, delivers exceptional natural insulation. It retains body heat, stays warm even when damp and resists odours thanks to its antibacterial properties. It’s the perfect choice for long mountain outings or winter expeditions.
Merino thermal tops ensure unmatched comfort for all outdoor pursuits. Once you’ve tried them, they quickly become an essential part of any ski or trekking wardrobe.
Care Instructions
Proper care extends the lifespan and performance of your base layers. Wash your technical underwear regularly to maintain breathability and prevent odours. Synthetic models can withstand frequent washing, while merino wool garments should be washed at no more than 30 °C with a gentle spin cycle. Avoid fabric softeners and air dry to preserve the softness and thermoregulating properties of the fabric.
