This REI Coop Base Layer Top is made of 100% Moreno Wool, providing superior warmth and comfort during your outdoor activities.

Its mild compression level and stretch feature ensure a snug fit and ease of movement.

The 1/2 zip design adds versatility to your layering options. This top fits a regular size large men and comes in a stylish blue grey stripe color.

Perfect for multi season sports and outdoor adventures, this base layer top is a must-have in your wardrobe.

I have worn this some over a couple of winters - not frequently- fits well as a stretch material.

The zip in the front allows you to control the degree of warmth - letting it out or stay in.

To me the design is more subtle than in your face.
