Which is warmer in deep cold?

The Mackage ADALI-SH is rated to -20°C and covers the thighs with 800 fill-power down. The Thorium has no stated rating and stops at the hip, so it suits layering rather than standing still in deep cold.

Which is better for climbing?

The Thorium. Its two-way zip clears a harness, the dump pockets hold shoes, the StormHood fits over a helmet, and the ripstop shell handles rock.

Which is lighter and easier to pack?

The Thorium, at 515 g and compressible. The Mackage is a 27-inch coat with leather pockets and a sheepskin collar, so it is bulkier to carry.

Is the Thorium worth about $500?

Its lowest daily price was $499.95 on October 28, 2026, and $500.00 on October 31, 2026. That buys a light, packable, abrasion-resistant down layer with a helmet-compatible hood. If you need thigh coverage and a -20°C rating, the Mackage is the better match.

Does either coat handle wet weather?

Both have water-repellent shells, the Mackage with a 3-layer membrane and the Thorium with a DWR finish. Neither is a rain shell, so heavy rain will eventually soak the down in either.

Which fits over a sweater?

The Thorium's regular, boxier cut leaves more layering room. The Mackage is fitted, so size up if you plan to wear thick knits under it.
