IRONHEART








Heavyweight Thermal Crew Neck Sweater IHSW-86-BLK - Black
US$250.00
Pickup currently unavailable
The Iron Heart IHSW-86-BLK Heavyweight Thermal Crew Neck Sweater in Black is available at Rugged Gentlemen Shoppe with fast local shipping and easy returns. Iron Heart produces many of its garments in limited runs, and popular sizes often become difficult to find once they sell through. If your size is currently available here, it can be secured while stock lasts.
This new style for Fall/Winter ’26 shares much in common with our IHTL-1700 long-sleeved thermal, but adds a ribbed hem to achieve a fit and appearance more akin to a sweater. The fabric used here is a 100% cotton waffle, heavier but not quite as tightly knitted as our standard waffle cloth. This creates a more substantial, textured knit that is warm yet breathable, and very soft on both faces. Along with the ribbed hem, the sweater is finished with matching cuffs and a crew neck, and constructed with four-needle flatstitch seams for strength and durability.
