L.L.Bean Polartec Power Dry Base Layer, Quarter-Zip Lightweight
Here's what other sites are saying:
The best synthetic moisture-wicking fabric we've found for cool-weather activities. Fast drying, it's our top pick for vigorous aerobic activities or for camping and travel. Antimicrobial Polartec Power Dry polyester is double plaited to wick sweat away from your skin, while the pill-resistant exterior quickly disperses it, keeping you warm, dry and comfortable. Flatlock seams give you a smooth fit. Thumb loops keep sleeves down. Lightweight fabric is ideal for moderate cold or more vigorous aerobic activities. Imported. Machine wash and dry.
