I had a Feathered Friends 20 deg bag. It weighed 3.3 Lbs. That was just too heavy. So, I sold the FF bag on Craigslist and bought this Alder MF. I already had a WM Mitylite bag (for warmer weather) , so I already knew they make great sleeping bags. The Alder MF is great, only weighs 1 Lb 15 oz and keeps me warm in all the types of weather I might expect here in the PNW. It is way more roomy than traditional Mummy shaped bags that taper down at the feet. I have a down hood that I can put-on if it gets too cold for just a sleeping cap. Thumbs up for this bag!
