It’s possible the Flylow Betty Women's Down Sweater is the perfect blend of warmth to weight ratio and baffled styling. A down sweater is one area of your core wardrobe you don’t want to skimp on, and the Betty hits all the high notes. 800-fill light, lofty, and warm goose down is quilted under Pertex® Quantum 30 denier fabric treated with a PFC-free DWR that is water resistant and repels damp. And while we could say “horizontal baffling” that hardly does justice to the strategic quilting which gives you smaller baffles across the shoulders and waist areas and larger ones in the body and arms, placing warmth where it’s needed, and adding shape and mobility to the sweater. Light, airy, and packable, this glides under a shell, and packs down into its own pocket for stuffing into a pack. It truly is the perfect insulating layer under a shell, as your around town autumn puffy, or the warmer you pull from your pack when you hit the summit. And it makes a nice little pillow for snoozing too.
