The TE-3991 is the powerhouse of the collection. Engineered for harsh conditions and maximum insulation, this ultra-heavyweight hoodie is built for those who need a rugged, dependable outer layer. Unlike lighter variants, the 3991 features a dense, high-gauge knit that acts as a natural windbreaker while maintaining a professional, stealthy appearance.
With its "blackout" styling and structured hood, it is the perfect choice for outdoor work, winter commutes, or achieving a high-end streetwear silhouette.
Maximum Thermal Retention: The thickest fabric in the line, designed specifically for sub-zero comfort when layered.
Stealth Aesthetic: Deep carbon-black finish with high-contrast minimalist branding for a sharp, clean look.
Industrial Durability: Crafted with high-abrasion resistance fabric to handle heavy daily use without thinning.
Oversized Comfort: A slightly structured, boxier fit that provides a modern look while allowing for thick under-layering.
Cross-Grain Cut: The body panels are cut on the cross-grain to resist vertical shrinkage and maintain the garment's length over time.
Double-Lined "Scuba" Hood: An extra-thick, dual-layered hood that holds its shape and provides superior head and neck warmth.
Hidden Media Port: Includes a discreet opening within the front pouch for headphone cable routing.
Overlock Safety Stitching: All interior seams are finished with five-thread overlock stitching to prevent any possible unraveling.
Heavy-Ribbed Trim: Extra-wide cuffs and hem to provide a secure seal against cold drafts.
