Spatzwear Basez Extreme Baselayer: BLACK S

Designed with one simple brief: create the warmest, most comfortable, quickest-drying, and best-designed winter base layer available. The Basez Extreme surpasses its predecessor, the award-winning Basez2, offering a whole new level of warmth and protection for the coldest conditions.

Advanced Insulation: Polypropylene yarn traps warm air against your skin, maintaining optimal temperature during intense activity.
Seamless Construction: Engineered for maximum comfort, with inside weaves and waffles that actively pull moisture away to keep you dry.
Wind-Stopper Technology: A breathable membrane across the chest provides a barrier against cold winds, keeping warmth locked in.
Tested in Extreme Conditions: After four winters of testing in the UK, Alps, and Pyrenees, the Basez Extreme has been shown to outperform multiple base layers, offering superior warmth and protection.
Ergonomic Fit: Long arms, a dropped rear, short front, and high neck design provide a close, unrestricted fit that works perfectly with outer layers.
