Out of all the good makers such as PHD, Western Mountaineering, RAB and Cumulus ect which would you say make the best lightweight sleeping bags that are durably made with honest temperature ratings and are of course very light and packable?
I've been doing a lot of research on ultralight bags and it seems that Rab's offerings are both overpriced and out-shined in every way by pretty much every other brand like PHD and Cumulus that make reasonably priced/performing bags but then there's Western Mountaineering being slightly higher priced but on paper they are that bit better in terms of weight and temp ratings than PHD/Cumulus however this is all on paper and there's no way of knowing which bag performs better in practical real world terms.
It seems the sleeping bag market is an absolute minefield! I'm really after a bag that weighs no more than 550gram, is durably made and is good to +5 celcius. The Cumulus Quantum 200 is an unbelievable 495 grams and is rated at 0 celcius whereas the identically priced PHD Minimus is only 25 grams lighter yet only rated to 5+ celcius. Whose the one being honest here, or are Cumulus really for real and make honestly-rated ridiculously lightweight bags?
