Columbia Men's Dark Mountain Heather Alto Pass Fleece Full-Zip Jacket

The Columbia Men's Alto Pass Fleece Full-Zip Jacket in Dark Mountain Heather brings a deep, earthy tone to a hardworking everyday fleece that performs just as well in the office as it does on the trail. Dark Mountain Heather is a rich, muted grey-green blend that reads as sophisticated rather than casual, making it well suited for professional settings where a purely grey or black fleece might feel too plain.

Built from 100% polyester fleece, this jacket delivers consistent mid-weight warmth and excellent breathability without adding unnecessary bulk to your silhouette. The full-zip front gives you complete control over ventilation, whether you need to vent during a brisk walk between buildings or zip all the way up against a cold morning.

Hand pockets offer practical storage and a resting place for your hands, and the Columbia woven patch logo on the left chest anchors the garment's authentic outdoor brand identity. The Alto Pass Fleece is designed with layering in mind.

Its clean, relaxed cut sits comfortably over a collared shirt or light mid-layer and fits underneath most shell jackets without bunching at the shoulders. The 100% polyester construction resists pilling over time and sheds moisture from brief exposure to light rain or morning dew better than cotton-blend alternatives.

For teams ordering through SWAGHQ, the Alto Pass Fleece Full-Zip Jacket is available with a minimum order quantity of 6 units, a 10-14 business day turnaround after art approval, and a full decoration guarantee. The Dark Mountain Heather colorway is especially popular for outdoor corporate programs, environmental organizations, and university outdoor clubs.
