Algonquin Lightweight Men's 100% Merino Wool T-Shirt
When the warmth of summer starts to peek out from winter, you'll be glad to reach for this amazing merino t-shirt.

Wear it as a base layer under your work shirt, or on its own during your next summer summit. The 100% merino wool construction is naturally soft, naturally odor-resistant, and machine washable without shrinkage. Whether you're climbing to a snowy winter peak or hiking to a beautiful summer summit, you'll fall in love with its everyday comfort.
