A premium 100 percent merino wool base layer, the Norrona PureUll Men's Zip Neck is built for year-round outdoor performance. The natural wool regulates temperature, wicks moisture, and resists odor, keeping you comfortable even when wet. It is the all-natural foundation layer for cold-weather skiing and everything in between.

Why we like it:

The pure merino wool is the whole appeal; it keeps you warm even when damp, manages moisture naturally, and stays fresh for days thanks to its odor resistance. A zip neck lets you vent heat the moment you start working.

Features and Functions:

The PureUll is made from Norrona's premium 100 percent merino wool in an ultra-fine 18.5 micron, mid-weight knit that is temperature-regulating, moisture-wicking, and naturally odor-resistant. The durable wool resists pilling, abrasion, and snagging, and is certified to the Responsible Wool Standard.

Fit and Sizing:

A regular fit with articulated arms gives full mobility and layers cleanly under a shell. True to size, cut to sit comfortably against the skin.

Bottom Line:

As an all-natural base layer for skiing, touring, and year-round use, the PureUll is best at temperature-regulating, odor-resistant warmth. A premium merino foundation for any cold-weather kit.
