Why the Murre ES 0 Was Designed for Women
Feathered Friends didn’t just take a men’s sleeping bag and slap a “women’s” label on it—they listened to real feedback from female adventurers and built the Murre ES 0 from the ground up. The result is a cold-weather sleeping bag that actually fits the way women sleep and stay warm.
The shoulder girth has been pulled in to reduce dead air space, while extra room was added through the elbows, chest, and hips—areas where women often feel restricted in standard bags. They also boosted insulation in the chest and footbox, which are common cold spots for women. These thoughtful changes don’t just make the Murre more comfortable—they significantly improve thermal efficiency, helping cold sleepers stay warm all night long. This is not just a women’s version; it’s a bag designed for how women truly sleep outdoors.
Performance in Real Conditions
The Murre ES 0 isn’t just warm on paper—it performs when it counts. Whether you’re camped in the snow or tackling early-season alpine routes, this bag delivers consistent, reliable warmth in sub-freezing conditions. Rated to 0ºF (-17.7ºC), it’s built to handle the coldest nights without fail.
For me, this bag was a revelation. After years of freezing even in so-called “cold-weather” bags, I finally stayed toasty warm all night—no fleece liner, no extra tricks. Just solid insulation and thoughtful design doing their job. I even tested it before a backcountry trip, and it exceeded expectations. The insulation in the chest and footbox kept my core and toes warm, while the hood and draft collar sealed in heat without feeling claustrophobic. In short, the Murre ES 0 transformed cold nights from miserable to comfortable—and that’s priceless in the backcountry.
Materials & Construction
The Feathered Friends Murre ES 0 is built with expedition-grade materials that balance warmth, durability, and weather protection. The outer shell uses Pertex® Shield EX combined with a 3-layer Pertex® Shield Air electrospun laminate, making it both water-resistant and highly breathable—ideal for damp tents or snowy nights. It shrugs off condensation while keeping the down insulation dry and lofty.
Inside, you’ll find a soft, 100% recycled 30-denier taffeta lining that feels smooth against the skin. The bag is filled with 900+ fill power goose down, responsibly sourced and certified to the Responsible Down Standard (RDS). Construction-wise, it features continuous baffles for adjusting down placement, tuck-stitch seams to prevent moisture wicking, and a 3D contoured hood that wraps warmth around your head. Add in a generous draft tube, a collar that blocks condensation, and a handy zippered interior pocket, and you’ve got a thoughtfully crafted bag made to thrive in harsh, cold environments.
Fit and Sizing
The Murre ES 0 is carefully tailored to fit the female body, offering a balance of thermal efficiency and comfort. Feathered Friends narrowed the shoulder width to reduce empty air space—key for staying warm—but added more room through the elbows, chest, and hips. This creates a shape that feels snug but never restrictive, even for side sleepers.
Available in Small (up to 5’3″) and Medium (up to 5’9″), the Murre is ideal for women looking for a bag that truly fits. Dimensions like a 55.5″ shoulder, 62″ elbow, and 57″ hip mean there’s enough space to move without letting warmth escape. The footbox is also thoughtfully designed with extra insulation and a 37” circumference, giving toes room to wiggle without freezing. Whether you sleep straight as a pencil or curl up like a cat, the Murre’s shape supports real comfort in real conditions.
Packed Size & Portability
For a winter bag loaded with high-loft down and rugged shell fabric, the Murre ES 0 packs down surprisingly well—but it does take some effort. The packed size is about 17 liters, which isn’t ultralight territory, but completely reasonable for a 0ºF bag. Getting it into the stuff sack can feel like wrestling a midsize alligator, but once it’s in, it fits nicely into most winter packs.
Weighing just under 3 lbs (2 lb 13.6 oz for Small, 3 lb 0.3 oz for Medium), it’s not ultralight, but it’s impressively light for the warmth it provides. You’ll appreciate that weight when temperatures drop and every ounce of insulation counts. It also comes with both a compression stuff sack for backpacking and a larger storage bag to preserve loft when stored at home. Bottom line: it’s a burly winter bag with reasonable packability, perfect for alpine climbs or multi-day snow camping trips.
Final Verdict: Is It Worth It?
If you’re a cold sleeper or regularly venture into sub-freezing conditions, the Murre ES 0 is absolutely worth the investment. Yes, it’s expensive—but when you consider how many cheaper bags fail to deliver true warmth, it’s money well spent. This bag combines elite materials, smart design tailored for women, and top-tier craftsmanship to deliver a truly reliable cold-weather experience.
From winter camping to high alpine ascents, the Murre ES 0 has proven itself as a bag you can count on. It’s warm, durable, breathable, and thoughtfully constructed in every detail. For me, it was the first time I ever stayed warm through a cold night—and that kind of comfort in the backcountry is priceless. If you’re ready to stop compromising and invest in lasting warmth, the Murre ES 0 is the dream bag you’ve been waiting for.
