Trail Running Baselayers

Running baselayers are the foundation of a comfortable run, helping regulate temperature, manage moisture and reduce irritation over longer distances. Whether you're pushing the pace on technical trails or training in changeable conditions, the right next-to-skin layer works hard to wick sweat, dry quickly and move naturally with your body.

Lightweight options are ideal for high-output efforts, while thermal and merino baselayers add warmth without bulk when the temperature drops. For colder or wetter runs, layer beneath a Trail Running Waterproof Jacket, and pair with supportive Trail Running Legwear to build a complete, trail-ready clothing system.

At Trekitt, our running baselayers are selected for real-world performance. They're breathable, durable and designed to stay comfortable from short sessions to ultra-distance days.
