Product Details

Thermajohn men's long sleeve thermal undershirt in solid black, designed as a lightweight base layer top for cold-weather wear. Smooth microfiber knit offers comfortable stretch and a close fit under shirts, sweaters, or outerwear. Top features a classic crew neckline, long sleeves, and a tagless printed neck label for added comfort against the skin. Simple, streamlined design works well for layering under workwear, outdoor gear, or casual outfits without added bulk. Inner print shows Thermajohn branding, size L, RN#153558, and fabric content of 92% polyester and 8% spandex with care instructions for machine wash cold and tumble dry low. Made in China.

Daily Cleaning: Use a soft brush or damp cloth to gently wipe away dirt. Avoid harsh chemicals. For mesh areas, use diluted mild detergent and a soft brush.

Drying: Air dry in a cool, shaded place after cleaning. Avoid direct sunlight or high heat, which can cause fading and glue deterioration.

Storage: Stuff with paper to maintain shape when not in use. Store in a dry, ventilated area to prevent mold. Rotate between multiple pairs to extend lifespan.

Usage Notes: Designed for basketball. Not recommended for hiking, long-distance running, or other specialized sports where different performance features are required.
