The Marmot Women's Jena Down Jacket features 700-fill down with Marmot's Down Defender treatment to keep you warm through damp spring and fall outings. Basically, the jacket's down is coated in a Durable Water Repellant (DWR) at the molecular level, acting as an insurance policy against wet weather to ensure your jacket retains its heat-trapping loft, despite the conditions outside (short of a full-on rainstorm or all-day deluge). How good is Marmot's Down Defender treated down, compared to the untreated competition' Well, Marmot claims that its treated down stays drier 10 times longer, maintains 150% more loft in damp conditions, and dries 30% faster than untreated down. Plus, the Down Defender treatment enhances the down's cluster integrity for longer lasting warmth. Aside from the jacket's midweight insulation that's great for chilly outings and casual wear, the Jena features a durable polyester mini ripstop shell that's also treated with a DWR for added resistance to passing showers. Its zippered hand pockets provide a place for small snacks and accessories when you're hiking and camping, and the elastic drawcord hem cinches tight for a great fit. In addition, this jacket uses Marmot's Angel-Wing Movement for freedom of motion when you're pitching a tent, hanging a bear bag in the wilderness, or retrieving items from hard to reach places in your pack.
