When we're running out of daylight and need to hustle along the last few miles of trail before setting up camp, we're grateful to have the Mountain Hardwear Phantom Sleeping Bag in our pack for its lightweight and compact design. The 30-degree sleeping bag is perfect for backpacking from spring through fall, with a two-way zipper that allows us to let excess heat escape on hot summer nights. The 800-fill down insulation and Nylon Ghost Ripstop material are incredibly packable while offering plenty of durability for reliable comfort season after season. The bag has been updated with a black lining that increases heat retention and allows the bag to dry out faster when we wake up with condensation on our tent walls.
