High-loft goose down anchors the Flylow Betty Women's Down Jacket, a packable, ridiculously warm layer for cold days. Oversized baffles give it a cozy, sleeping-bag feel, while the water-resistant shell keeps the warmth working. It is the warm, stuffable jacket you reach for when the temperature really drops.

Why we like it:

The oversized baffles are the cozy signature; they let the down fully loft for a warm, pillowy feel, and the whole jacket self-stows into its own pocket to become a camp pillow. Pit zips keep you from overheating when you get moving.

Features and Functions:

The Betty is filled with packable 800 fill-power goose down certified to the Responsible Down Standard, wrapped in a tightly woven Pertex Quantum shell with a PFAS-free water-repellent finish. Oversized baffles maximize loft, 6-inch pit zips regulate temperature, and a roomy internal pocket lets the jacket self-stow into a pillow.

Fit and Sizing:

A regular fit settles over a baselayer or fleece. True to size, with a comfortable cut that lets the down loft.

Bottom Line:

As a packable insulator or a warm standalone layer, the Betty is best at high-warmth, low-weight down for cold conditions. The cozy puffy you bring on every cold-weather trip.
