Arch Rock 1/4-Zip Sweater – Men’s

What Our Gearhead® Experts Are Saying:

“This sweater has a great balance of durability and comfort. The 5-gauge merino knit feels substantial and warm without being overly bulky, and it regulates temperature well on cold days. I like using the zip to vent heat during activity and sealing it up when the wind picks up. It’s a reliable insulating layer with timeless style.”

When frost settles on the trail and the air turns sharp, we reach for the Arch Rock 1/4-Zip Sweater for dependable warmth. Royal Robbins crafts this classic layer from 100% Responsible Wool Standard merino wool, delivering natural performance built for cold-weather adventures.

The 5-gauge knit offers durable structure and cozy insulation, while merino’s breathable, moisture-wicking, and odor-resistant properties help regulate temperature through changing conditions. A high collar and 1/4-zip closure give us the flexibility to seal in heat or dump excess warmth on the move. Finished with a timeless Fair Isle pattern and standard fit, this insulating layer blends mountain-ready function with heritage-inspired style.
