Teneqa 850

My cumulus teneqa 850 is very high quality and a good value, I recommend the manufacturer highly. Keep in mind that if you buy from Poland or most of Europe while you're in Norway you'll have to pay toll as Norway is not part of the EU

Get the Cumulus Teneqa 850 or Alaska 1100 are by far your best options in the EU quality/money wise. US, no clue with the current tariffs. Probably Western Mountaineering or Feathered Friends. When I was in Kyrgyzstan, Temps dropped to -5C in August, but if I slept in my down jacket and -1C comfort UL sleeping bag, I was more than fine.

Goose down is generally superior to duck down. I advise you buying goose down minimal 850FP. The Achilles heel of a 3-season sleeping bag is its ability to cope with damp, cold (weather and tent) conditions!!! I contacted Western Mountaineering (WM), Peter Hutchinson Designs (PHD), Helsport, Cumulus Outdoor. Conclusion: as a rule of thumb, the comfort temperature for a 'cold sleeper' is a sleeping bags 'T Comfort' rating minus approx. 10C, in other words if you want feel comfortabel around 0C you need a sleeping bag with -10C 'T Comfort'; I advise you / 'cold sleeper' buy from a manufacturer which ALSO offers: \-an inner sleeping bag (e.g. Cumulus Panyam 600); \-an outer synthetic bag (e.g. Cumuls Polar Overbag for handling damp, cold conditions); \-winter / expedition sleeping bags (e.g. Cumulus Excuistic, Teneqa); \-Overfill, additional overfill; WM good quality, but insufficient expedition sleeping bag supply in Germany, Netherlands, France. PHD good quality, but very expensive, very slow email accessibility. Helsport too few specifications. Buy a sleeping mat with R-value suitable for 0C! I'm in doubt about hydrophobic goose down, because: \-Cumulus Outdoor quote "... For over a decade we’ve used hydrophobic down in many Cumulus® products. Thanks to a special treatment it performs better in damp conditions, holding loft longer and drying faster. ..."; \-WM quote "... Through our own testing, we’ve found that the performance benefits of hydrophobic treatments on high-quality down are often overstated. Premium, untreated goose down naturally contains water-repellent oils — which makes sense, given that geese spend much of their lives in wet environments — and these oils help maintain loft and insulation over time. Hydrophobic treatments tend to wash out much like a DWR and can strip away those natural oils during application, potentially reducing long-term performance. Combined with the strong water resistance of our shell fabrics, we don’t feel hydrophobic down provides a meaningful advantage and, over the lifetime of the product, may actually work against it. ..."; \-PHD quote "... We are currently monitoring the development of hydrophobic downs, in which DWR (Durable Water Repellent) chemical treatments are used as a coating. The idea is that the treatment both slows down water absorption and stiffens the tendrils of the down cluster to increase fill power. However, the longevity of treated down and the speed of deterioration of fill power is a concern to us. High quality, well processed natural downs are actually already very hydrophobic. In addition, we make many of our products in water resistant fabrics to protect the down from condensation found in tents and snow holes. And where necessary, to protect even further, we offer fully taped waterproof shells. ...";

Before you buy, I'd read through Dan Timmerman's blog: [https://timmermade.com/blog/](https://timmermade.com/blog/) He says it better than I will. But it comes down to wrapping yourself with the right thickness of insulation for the least amount of weight and money, which means you need a bag that fits your body and sleeping position, and uses the right amounts of top-notch materials. **Keep in mind insulation is a complete system**. It includes sleeping pads and shelters. \-A thin CCF pad under an air pad boosts R-value for cheap. Decathlon's foam roll is 210g and 9 Euro. GG thinlite is half the weight and double the price, which is still cheap. \-A bivy bag can easily add 5C to your warmth because it prevents wind from stealing your warmth. You can find them on aliexpress for \~30 Euro in the 250g gram range, or from cottage makers in US for more $ and less g. Keep in mind, you do still want good ventilation to prevent condensation. Feathered Friends is gold standard. Quality is top. The price reflects that. Any of the FF 10F (-12C) or 0F (-18C) bags could work. Don't get confused by names. Just look at the girth specs, and fit to height. **Maybe** in your price range with the USD being cheap right now. I think the Cumulus Panyam and Teneqa series check all the boxes at a fair price. Choose the weight you need, add an extra 60g of down, and size it to fit yourself. Good options on website. You'll come in right around 400-500 Euro. Cheaper than that is Aegismax. \-G is the 850 FP goose down UL winter series, Choose your weight and length. Is it totally dialed in? No, but it's a really solid choice. \-D is the 650 FP duck down budget series. Adequate, not ideal but worth mentioning though My best personal experiences have been with \-Feathered Friends Flicker 20 (-7C) for general 3 season use, which I like for versatility. It works down to actual rated temp with the right shelter, pads, campsite selection, clothing. \-Aegismax Mini 6C which is good for summer use (which is half the year where I live), but was impressed with brand.

Take a look at cumulus bags. They can do custom fill (up or down, “waterproof” different fabrics etc ) and custom sizing for it as well if you wish. Not cheap but personally I think they’re the best down bags on the market.
