Product Insights & Style Tips
The Mountain Warehouse Alaskan Long 3-in-1 jacket sits at the intersection of rain-ready and trail-smart. Made entirely of polyester, it seals out weather with taped seams and a full zip under a storm flap. With a 10000mm waterproof rating and 5000g/m2/24hrs breathability, it keeps you dry without feeling stifled. A grown-on hood with a toggle shields the wind, while the detachable inner jacket adds warmth when temperatures drop.
Cut in a longline silhouette, it skims over knits and fleece while offering full coverage. Two side pockets cradle cold hands and carry small essentials, while the outer shell's zip, storm flap and stud closures keep the front neat. The cuffs adjust with hook-and-loop straps for a snug seal, and the inner layer detaches for lighter wear when the weather shifts. Layer it over a sweater on damp commutes or beneath a shell on tougher days, and it travels from city streets to open trails with ease.
Mountain Warehouse leans into practical outerwear with this 3-in-1 piece, built to handle changing weather without drama. The longline shape reads as city-friendly yet ready for weekends away, pairing with denim, cargo pants, or athleisure for a weather-ready look.
