Mountain Hardwear Phantom

The Phantom 15 is rated for temperatures down to 15°F (-9°C). It is designed as a high-performance bag for cold-weather alpine conditions, though personal warmth preferences and your sleeping pad's R-value will significantly impact your comfort level.

The shell uses the same lightweight, 100% recycled fabric found in the Ghost Whisperer series. While it is impressively light and packable, it is a technical fabric that requires care around sharp objects like crampons or jagged rocks.

Thanks to the 800-fill goose down, this bag is highly compressible. It packs down to a very small size, making it an excellent choice for climbers or backpackers who need to maximize space in their pack without sacrificing warmth.

Yes, the Phantom 15 uses RDS-certified down. This certification ensures that the down comes from animals that have been treated ethically and responsibly throughout their lives.

The shell fabric is water-resistant, which helps protect the down insulation from light moisture and condensation inside a tent or snow cave. However, it is not waterproof, so you should still use a dry bag or pack liner to keep it completely dry during heavy rain or wet conditions.
