Compare the Luna Jacket and Larkspur Jacket on warmth, weather resistance, and packability so you can pick the right women's insulated jacket for camp and cold days.
Quick answer
Choose the Luna Jacket if you want a lightweight, packable 650-fill down layer for camp and everyday wear. Choose the Larkspur Jacket if you need synthetic insulation that manages moisture during active backcountry days. Both are women's insulated jackets, but they solve different problems: dry cold versus sweat and wet cold.
How the Luna and Larkspur Differ
The Luna Jacket uses 650 Fill Power Downtek water-repellent down and Signature Diamond Quilting. That construction keeps insulation in place with less stitching, so the jacket stays warm with less weight and bulk. It is packable enough to stash in your pack, which makes it a good match for camp, town, and trips where you are not generating much sweat.
The Larkspur Jacket uses synthetic insulation with a breathable membrane. The membrane resists water from the outside while drawing moisture away from your body and trapping heat close to the skin. It is built for long backcountry days where you move, sweat, and then cool down. Synthetic insulation keeps working better than down when moisture is present.
Warmth and Weather Trade-Offs
Down gives more warmth per ounce, and the Luna's 650-fill Downtek down is treated to resist water. That makes it the lighter, more compressible choice for dry cold. The trade-off is that down loses loft if it gets soaked, so it is less forgiving in sustained wet conditions.
The Larkspur prioritizes moisture management over pure warmth-to-weight. Its synthetic fill and breathable membrane handle sweat and damp air better, but it will not pack down as small as the Luna. If you run hot or hike hard in cold, rainy places, that trade-off usually favors the Larkspur.
Fit and Layering
Both jackets come in Color and Size options. The Luna's jogger-style design is not mentioned in the catalog facts, so do not assume a relaxed fit; check the size chart. The Larkspur is described as body-mapped, which usually means insulation is placed where you need it most. If you plan to wear either jacket under a shell, size up or test the combo. If you want it as a standalone outer layer, your normal size is the safer start.

- Layering and fit: Luna is a standalone puffy; Larkspur is body-mapped. Both offer Color and Size. If you layer under a shell, size up or test the combo. Choose based on whether you run hot or cold and whether you will wear a shell over it.
