Coldpruf Men's Authentic Dual Layer Wool Base Layer Top

Our insulated shirt for men features dual-layer engineering with a Merino wool fabric blend that traps body heat between layers to provide a natural, chill-blocking barrier of warmth. Designed to fit loosely on the body, our men's thermal long-sleeve shirt boasts a generous cut, tagless design, and flat seams for a smooth, ultra-comfortable fit and feel.

The AUTHENTIC two-layer garment has been specifically engineered with our ColdPruf Insulation System to trap air between the layers of fabric and provide a natural warmth shield. The Outer Layer of MERINO WOOL, nature's warmest fiber, is blended with Combed Ring Spun Cotton and Nylon, and paired with 100% Combed Ring Spun Cotton on the Inside, offering the desired WARMTH and COMFORT in very cold to extremely cold weather conditions during low to medium activity.

Equipped with convenient stay-put ribbed cuffs and a drop tail that provides coverage without restricting freedom of movement, our tagless thermal shirt is the perfect choice for cold weather apparel. Our men's thermal shirt allows for minimal layering in extremely cold conditions during low- to medium-exertion activities, making it versatile for both casual and active wear.

The fabric type is 100% Cotton Inside, with a blend of 65% Cotton, 25% Merino Wool, and 10% Nylon on the Outer Layer. The garment is machine washable and imported. Our men's long johns are available in regular sizes from Small to 3XL, ensuring a comfortable and customized fit for a wide range of body types.

THE AUTHENTIC - NATURAL WARMTH AND COMFORT. This two-layer thermal shirt is engineered to provide superior insulation and a cozy, comfortable experience, even in the harshest of cold weather conditions.
