The Mountain Hardwear Men's Bishop Pass 15F/-9C Sleeping Bag is a roomy mummy shaped bag for all-around use. Car camping, backpacking, climbing weekends and more. The bag has been stuffed with enough 650 fill power down to provide warmth on nights that drop down to 15°F. The nylon interior and exterior is soft against the skin yet durable against daily use inside the tent. Featuring a DWR finish, it sheds light moisture such as tent condensation or a light rain, helping protect the insulation inside. Plenty of wiggle room for rolling over plus a draft collar to prevent chills from sneaking their way inside. Tuck your phone into the internal stash pocket and drift off as the crickets serenade you through the night.
