This bulk pack includes 24 men’s thermal underwear sets in black, each with a matching long-sleeve top and bottom. These thermals are practical, versatile, and easy to pair with any outfit. Buying in bulk makes them a cost-effective solution for families, teams, schools, shelters, charities, or resale.

Each set is designed as a warm yet lightweight base layer, providing reliable insulation without adding unnecessary bulk. The snug, tight-fitting style helps trap body heat, while ribbed cuffs at the wrists and ankles help reduce heat loss, making them ideal for cold autumn and winter days.

Constructed from a durable polyester-blend fabric, these thermals are breathable, sweat-wicking, and quick-drying to keep you comfortable all day long. The four-way stretch material allows for flexibility and freedom of movement, while reinforced seams ensure long-lasting wear.

Assorted sizes from S-2XL, each set features an elastic waistband for comfort and tapered bottoms that fit neatly into boots, making them practical for work, outdoor activities, or everyday layering.

Perfect for any winter occasion, these thermal underwear sets can be worn as a base layer under formal or casual outfits, used for outdoor activities like skiing, hiking, snowboarding, or hunting, or enjoyed as cozy loungewear or pajamas at home.
