Rab Alpine Light Down Jacket

Jump to: Our Verdict / Features / Specifications

The Montbell Alpine Light Down Jacket combines impressive warmth with minimal weight and excellent packability. Suitable as a mid-layer or outer layer in moderately cold and dry weather.

Montbell says: 

The Alpine Light Down Series is our highly functional mid-layer for comfortable backcountry activities. The secret to the warmth of these garments not only relies on the high lofting 800 Fill Power EX Down, but the inherent wind shedding ability of the 20-denier Ballistic Nylon shell.

Our Verdict

The Montbell Alpine Light Down Jacket is a premium, lightweight and packable insulated layer designed for active backcountry use. Stuffed with 800-fill power hydrophobic down, it provides impressive warmth for its minimal weight and compressible packability.

The 20D ballistic nylon ripstop shell has a water-resistant finish to shed light moisture, while the sewn-through construction keeps the down from shifting. Despite being so thin and light, the jacket cuts wind exceptionally well thanks to the tightly woven face fabric.

Functional features include a micro-fleece-lined collar, hem cinch cord, elastic cuffs, and four pockets, including two zippered hand pockets. The athletic fit layers easily without excess bulk.

While not intended for extreme cold conditions, the Alpine Light Down Jacket excels as a highly efficient mid-layer or outer layer in cool to moderately cold and dry weather. It strikes an exceptional balance of furnace-like warmth, lightweight packability, and active insulation performance that few other down jackets can match.
