Midweight Men's Wool 1/4 Zip - 100% Merino Wool

Adaptable Warmth for Changing Conditions: The Men’s Midweight Merino Wool 1/4 Zip

Built for days when temperatures shift as quickly as the terrain, the Men’s Midweight Merino Wool 1/4 Zip delivers adaptable warmth in a highly versatile technical layer. Made from 100% merino wool, it combines natural temperature regulation with a ventable quarter-zip design, backpack-friendly construction, and thoughtful details for extended comfort on the trail, at camp, or anywhere cold weather takes you.

Thoughtful Design & Materials

100% Merino Wool Construction: Made entirely from fine Australian merino wool for natural warmth, breathability, moisture management, and next-to-skin comfort.

Midweight Interlock Knit: The 245 g/m² fabric provides substantial insulation without unnecessary bulk, making it equally capable as a base, mid, or insulating layer.

Fine 18.5-Micron Fibers: Soft merino fibers create a comfortable feel against the skin for extended wear during long days outdoors.

Certified Materials: OEKO-TEX® STANDARD 100, Woolmark®, and Responsible Wool Standard® certifications provide added confidence in material quality and responsible wool sourcing.

Performance You Can Rely On

Natural Temperature Regulation: Merino wool helps retain warmth when temperatures drop while remaining breathable as your activity level increases.

Adjustable 1/4 Zip Ventilation: Close the zipper and use the mock neck for additional warmth, or open it to quickly release excess heat during climbs and high-output activity.

Moisture Management: Merino naturally absorbs moisture from the skin and releases it into the air, helping maintain a more comfortable microclimate throughout changing conditions.

UPF 50+ Protection: High-level UV protection adds another layer of performance for exposed trails and long days outside.

Built for Movement & Layering

Yoked Shoulders: Offset shoulder seams help reduce pressure and irritation beneath backpack straps for greater comfort over long distances.

Integrated Thumbholes: Keep sleeves securely positioned while layering and provide additional hand coverage when temperatures fall.

Flatlock Seams: Smooth construction helps minimize friction and chafing during extended movement.

Zipper Garage: A protective fabric barrier prevents the zipper from resting directly against your skin.

Light & Packable: Provides substantial midweight warmth while remaining easy to incorporate into hiking, camping, and travel gear systems.
