Western Mountaineering Badger MF Sleeping Bag – 15°F, 7ft Left Zip, MicroLite XP

Overview

The Western Mountaineering Badger MF is a roomy, high-performance sleeping bag designed for serious cold-weather nights without sacrificing mobility. It combines a generous shoulder and hip area with premium down insulation, giving you a comfortable blanket of warmth that doesn’t feel constricting in a mummy silhouette.

With an inside shoulder girth of 67 inches, a hip girth of 58 inches, and a foot area of 41 inches, the Badger MF provides noticeable space where you need it most. The weather-ready MicroLite XP shell trades stiffness for breathability and weather resistance, while the 23 ounces of 850+ fill goose down loft to about 6 inches, offering a substantial yet compressible warmth that adapts to varying camp conditions.

Design details are proven to help you stay warm and comfortable through the night. A full-length #5 YKK zipper is paired with an insulated draft tube and a full down collar that keep warmth in where it matters most. The hood is intentionally large and forgiving, wrapping around your face without the need for intense cinching. Altogether, the Badger MF balances the convenience of a large-volume bag with the efficiency of premium down and thoughtful construction.

In practice, this bag supports a range of outdoor adventures—from shoulder-season excursions to longer backcountry trips where weight, packability, and durability matter. The bag weighs 2 lb 10 oz and compresses to a roughly 8 by 17 inch stuff sack, making it a practical option for setups that prioritize warmth with reliable packing performance.
