Cotton Plus Heavyweight Thermal Shirt - Black

Heavyweight Thermal

The Cotton Plus Heavyweight Thermal Shirt is a cold-weather base layer built to hold warmth close to the body under a jacket, or to be worn on its own as a heavy long-sleeve shirt. The thick cotton-and-polyester knit traps heat without feeling clammy, which makes it a good first layer for cold mornings on the range, in the field, or around the yard. In plain black, it stays low-profile under anything you put over it.

Features

• Heavyweight Knit — A thick, dense fabric that holds more warmth than a standard tee and stands up to repeated wear.
• Cotton-Polyester Blend — Cotton for next-to-skin softness, polyester for shape retention and quicker drying after a wash.
• Crew Neck Collar — A close round neckline that sits under a shirt or jacket collar without bunching.
• Ribbed Cuffs — Snug knit cuffs at the wrist seal in heat and stop the sleeves riding up under gloves or outer layers.
• Long Sleeves — Full-length sleeves cover the forearms for warmth as a base layer or a standalone shirt.
• Black Colorway — Solid black hides dirt in the field and disappears under any outer layer.
• Base Layer Fit — Cut to wear close to the body so it layers cleanly without adding bulk.
• Multiple Sizes — Offered across a size range so you can match it to your layering system.

Build And Fit

Cotton Plus builds this shirt from a cotton-polyester blend chosen to balance comfort against durability. The cotton content keeps it soft against the skin, while the polyester helps the knit keep its shape through the wash and dry faster than straight cotton. Worn as a base layer, it traps a pocket of warm air next to the body; worn on its own, it works as a heavy everyday long-sleeve. Size up one if you plan to wear it over other garments.
