Introduction
When it comes to skiing and snowboarding, your base layer is one of the most important layers you’ll pack. Designed to regulate temperature, wick away sweat, and keep you comfortable, base layers work hand in hand with your outerwear to maximise performance on the slopes.
In 2025, UK skiers are turning to eco-friendly base layers - high-performance, sustainable options made from recycled materials that deliver warmth and breathability without compromising the planet.
Why Base Layers Are Essential for Skiing
Your ski jacket and trousers protect you from wind, snow, and rain, but they don’t regulate your body’s internal temperature. That’s the job of a base layer. A good ski base layer will:
• Trap warmth while remaining breathable.
• Wick away sweat to keep you dry.
• Stay comfortable against the skin during long, active days.
Without one, you’re more likely to feel clammy on the lifts and cold halfway down the run.
Why is cotton on the mountain a problem?
Cotton absorbs moisture and stays wet, clinging to your body and losing insulation. On the slopes, this means chills, discomfort, and even a higher risk of hypothermia. Rule of thumb: cotton is never suitable for ski base layers.
What About Wool Base Layers?
Merino wool is often marketed as a premium choice for skiing, thanks to its natural warmth and odour resistance. But wool isn’t for everyone, some people find it itchy, irritating, or prefer not to wear animal-derived products. Luckily, modern recycled synthetics now rival wool in comfort and performance, while being vegan-friendly and more durable.
Key Features to Look for in Eco-Friendly Synthetic Ski Base Layers:
When choosing sustainable base layers in the UK, focus on:
• Moisture-Wicking Performance: Recycled polyester and elastane blends excel at moving sweat away from the skin.
• Odour Resistance: Many eco-friendly synthetics include built-in odour control, keeping you fresh.
• Sustainability: Look for recycled fabrics, low-impact dyes, and certifications such as GRS (Global Recycled Standard).
• Fit & Comfort: Flat-lock seams, stretch, and ergonomic designs prevents irritation and enhance mobility.
Should Ski Base Layers Be Tight or Loose?
Ski base layers should fit snug, but not restrictive. A close fit allows the fabric to effectively wick sweat away from your skin and trap warmth, while still allowing freedom of movement.
• Too tight: May restrict movement and feel uncomfortable.
• Too loose: Moisture won’t transfer properly, leaving you damp and cold.
Think of base layers as a “second skin”, supportive, stretchy, and comfortable.
