The Basez Extreme was 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 uses polypropylene yarn to trap warm air against your skin, maintaining optimal temperature during intense activity. The seamless construction is engineered for maximum comfort, with inside weaves and waffles that actively pull moisture away to keep you dry. Wind-stopper technology, featuring a breathable membrane across the chest, provides a barrier against cold winds, keeping warmth locked in. 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. The ergonomic fit includes long arms, a dropped rear, short front, and high neck design, providing a close, unrestricted fit that works perfectly with outer layers.
