Mountain Hardwear Bishop Pass Sleeping Bag

Yes, with a temperature rating of 0°F, this bag is designed for cold-weather conditions. It features 650-fill down insulation and a draft collar to help retain heat during freezing nights.

The Bishop Pass has a compressed volume of 11.3 liters. It includes a compression sack, making it relatively compact for a 0-degree bag, though it is best suited for backpacking trips where pack volume is a priority.

The Performance Plus mummy shape offers a slightly roomier cut than a traditional, restrictive mummy bag. It provides the thermal efficiency of a mummy design while allowing for a bit more movement, which is helpful if you tend to shift positions while sleeping.

The DWR (Durable Water Repellent) finish makes the shell water-resistant, meaning it will shed light moisture and condensation. However, it is not waterproof, so you should still use a tent or bivy sack in heavy rain or wet snow.

Because this bag comes in both left- and right-hand zipper configurations, you can zip a left-zip bag to a right-zip bag if you have both versions. This is a great feature for couples who want to share warmth.

You should store the bag in the included mesh storage bag in a cool, dry place. Avoid keeping it compressed in the stuff sack for long periods, as this can damage the down's loft and reduce its insulating performance over time.
