Built for cold-weather campaigns from city grid to high ridge, the Sherpa-Lined Interval elevates our performance denim jacket into a winter-ready essential. We kept everything that made the original Interval a capable daily layer—its raw Mt. Vernon Mills stretch denim, articulated mobility, and discreet zippered storage—and fortified it with heat-retaining materials engineered for modern conditions. At its core is 12.25 oz raw stretch denim, a heritage-grade fabric milled in the USA that breaks in with your life and maps to your movement over time. Inside, a 306 g/m² sherpa lining delivers immediate thermal gain without the bulk, while quilted nylon sleeves with 80 g/m² insulation allow for smooth layering and quick transitions on the move. The result is a jacket that blends the honesty of workwear, the discipline of technical design, and the warmth required when winter pushes back. Dual zippered chest pockets and zippered hand pockets—each equipped with internal dividers—keep essentials secure and accessible without disrupting your workflow. YKK metal hardware and TAD-branded shanks reinforce every critical touchpoint, ensuring long-term durability as the denim matures and develops signature patina. Made proudly in the USA, the Sherpa-Lined Interval is built for those who demand capability—crafted for the season when resilience becomes non-negotiable.
