Odlo ACTIVE X-WARM Technical Base Layer

Designed for mixed-use, the Odlo ACTIVE X-WARM technical base layer is intended for those engaging in intense activities in extremely cold weather, whether skiing, winter hiking, or any outing in extreme conditions. Its double-layer construction in key areas provides targeted insulation, while its slim fit ensures a snug, close-to-the-body feel without adding bulk. A thermal base layer designed for those who don’t slow down when temperatures drop.

The X-Warm system in the Odlo ACTIVE X-WARM: insulation and moisture management combined

At the heart of this thermal base layer, the X-Warm temperature control system combines insulation and breathability to keep the body warm without trapping excess heat generated during physical activity. The double-layer insulation, concentrated in key areas, effectively protects against low temperatures—exactly where the cold is felt most. At the same time, enhanced moisture management quickly wicks away sweat, minimizing the damp feeling that cools the body during breaks or descents. The fabric’s quick-drying properties extend this thermal comfort throughout your ride.

A soft, stretchy fabric for complete freedom of movement

The recycled polyester blend, with an elastane insert, gives the garment four-way stretch. This elasticity moves with you without restriction, whether you’re making repeated bends while skiing or taking strides on a hike. The fabric’s soft feel against the skin prevents irritation during long outings, even when worn next to the skin. The close-fitting cut optimizes thermal efficiency by reducing unheated air pockets between the garment and the skin.

An eco-friendly approach and lasting breathability

All of the main fabric is made from recycled polyester, an approach consistent with outdoor activities that are mindful of their environmental impact. The base layer is certified STANDARD 100 by OEKO-TEX®, guaranteeing that it contains no harmful substances. The odor-control technology, based on mint-derived active ingredients, ensures long-lasting freshness during prolonged exertion, without requiring frequent washing between uses.

The Odlo ACTIVE X-WARM technical base layer is a versatile thermal base layer, suitable for skiwear and winter hiking layering, available in Black in sizes S through XL.
