The Rab Women's Microlight Down Jacket will warm your core whether you hike across a snow-capped landscape, skin up wintery peaks, belay your partner up an alpine ascent, or hang out by a cold campsite. Its Pertex Microlight outer fabric makes this jacket very lightweight, surprisingly durable, windproof, and highly breathable, and the nylon ripstop lining helps the jacket slide easily over your layers and boosts durability on the inside. Between the fabric layers, hydrophobic Nikwax-treated 700-fill European goose down brings a sweet warmth-to-weight ratio for moderately cold and slightly soggy days, or chillier adventures when you'll be moving a lot. The down also means this jacket packs down small—Rab included a stuffsack, too—so you'll always have space to bring it along.

The Microlight's slim fit helps avoid the super-puff look, and it means you can layer a waterproof shell over this jacket when weather conditions get unfavorable. The jacket's Lycra-bound cuffs and hem drawcord keep undesirable breezes out, and two hand pockets warm your fingers. Behind the zipper, an insulated storm flap seals out breezes and drafts, and the soft chin guard lets you duck your head against the cold without rubbing your skin raw.
