Buying Guide
- Material and warmth: Merino grid fleece blends provide odor resistance and warmth even when damp. For high-output activities, a midweight fleece with a zip or collar option helps regulate temperature.
- Layering versatility: Look for pieces with adjustable cuffs, zip pockets, and zip collars to adapt to changing conditions and activities, from early morning hunts to afternoon climbs.
- Mobility and fit: Stretch fabrics and articulated sleeves improve range of motion for movement-heavy activities like bow tuning or climbing.
- Durability and care: Merino blends and fleece with reinforced cuffs withstand abrasion during outdoor work. Consider ease of washing and quick-dry properties for rugged use.
- Weather adaptability: Midweight fleeces should perform in cool-to-moderate conditions and layer well under shells in cold snaps or over base layers in milder days.
