Black Diamond Men's Coefficient LT Crew

• Grid fleece wicks and breathes while you work
• Thumb loops keep sleeves in place and protect the backs of your hands
• Gusseted underarms move with you on climbs
• Only 148g, so it packs down small
• Flatlock seams help avoid chafing

• Fabric: Polartec Power Grid lightweight fleece, 90% polyester and 10% elastane, 119gsm
• Fit: Slim
• Weight: 148g
• Sleeves: Elastic thumb loops
• Underarms: Gusseted
• Seams: Flatlock stitching

• Cold-morning mountain runs
• Alpine approaches and ski touring
• Using as a baselayer under a shell

Less suited to: Warm days or runners who prefer a looser top; it is a slim fit baselayer, not a casual tee. For that, look at Men's Tops.

Light fleece baselayers can be bulky or too hot. The Coefficient LT is a stretchier, lighter take on Black Diamond's popular Coefficient, and the grid lining is a practical upgrade for hard efforts. It fills a gap for cold starts in the hills.
