Product Details
The N-Ferno® 6436 long sleeve lightweight base layer shirt is designed for comfortable warmth in mild to cold conditions, made with lightweight and breathable stretch fabric. The shirt features a 180g polyester-spandex performance material that provides warmth without the bulk typically found in heavyweight base layers. Its smooth and stretchable fabric allows for easy layering under sweatshirts and jackets, while a long tail ensures full coverage. This base layer shirt is designed to sit slightly looser against the skin to enhance breathability and mobility, creating an air gap for additional insulation. Raglan sleeves and wider underarms facilitate a full range of motion. The shirt incorporates moisture-wicking technology and an anti-odor treatment, ensuring that workers stay comfortably fresh, dry, and warm throughout the day. With flatlock seams and a tagless interior, it prevents irritation and chafing. The N-Ferno® 6436 is ideal for those in construction, transportation, warehousing, refrigerated areas, and other demanding environments, as well as for various weekend activities such as hunting, climbing, running, cycling, and skating. To complete the set, it can be paired with the N-Ferno® 6481 lightweight base layer pants (sold separately). For those needing heavier-duty warmth in cold temperatures, the N-Ferno 6435 midweight base layer shirt and 6480 midweight base layer pants are also available.
