Carhartt Yukon Extremes® Active Jac – Extreme Cold Insulated Work Jacket

Born From Work. Built For The Coldest Temperatures On Earth.

When temperatures plummet to record lows, most gear taps out. The Carhartt Yukon Extremes® Active Jac is engineered for those who can't afford to quit. Wrapped in a battle-hardened 500-denier Cordura® nylon shell and packed with 150g 3M™ Thinsulate™ featherless insulation, this jacket delivers Carhartt's highest warmth rating — Level 4: Extreme Warmth — without the bulk that slows you down. Triple-stitched seams, Rain Defender® DWR coating, and Wind Fighter® technology mean the elements never win. This is the jacket you reach for when the thermometer quits.

Yukon Extremes® — Engineered for Level 4: Extreme Warmth

A Level 4 Extreme Warmth rating is reserved for Carhartt's most capable cold-weather gear — outperforming conditions where ordinary insulation fails. Lighter and more flexible than traditional heavy-duty outerwear, yet uncompromising in durability and protection. The Yukon Extremes® series combines 3M™ Thinsulate™ featherless insulation with CORDURA® reinforcement to repel wind, rain, sleet, and snow — keeping you moving when it matters most.
