Polarmax combined pure Merino wool with Acclimate Dry fibers and added spandex to create a base layer hybrid that is warm, comfortable, and easy to move in. Natural Merino wool is inherently thermal retentive; it traps air in its fibers, keeping insulating warm air close to your body.

Features:

• Crew neckline
• Acclimate Dry hydrophobic yarns
• Midweight warmth, relaxed fit
• 67% Polyester / 28% Merino Wool / 5% Spandex; 175 gsm
