New to the game and tried out mummy bags, but didn't like the constraint at all. REI salesperson recommended the Nemo bag.I liked that i could bend my knee and be comfortable. I took this bag on two weekend trips so far this season. It did seem too big/long to stuff into my pack, but a little force and it sits in the bottom of the pack just fine. Trip 1: Overnight low in high 30s/low 40s with very little wind and no rain. Bag was comfy and I actually got pretty hot with baselayers on. Then again, the bag is rated at 25F. Trip 2: Overnight low in the low teens and very windy. Obviously this is lower than the 25F rating, but I was ok with baselayers, socks, down sweater and wool cap. There were cold spots because of the extra room, but my friend in his mummy bag experienced cold spots as well.Blanket fold is awesome, really helped with covering face from wind. Pillow pocket is a nice feature, but side sleepers like me prefer to move the pillow around. Nocturne is next buy
I've got national certification as a lousy sleeper and need lots of room to flop around. I compared this bag to a lot of others since I was concerned with weight and the fact that there's more "air pocket" inside. Although it was slightly heavier than what I wanted; that fact is overcome by the shear comfort it provides. I've used it around 5-6 times down to 30 degrees without any hint of chill. The material is plush and silky. But, the main reason to consider it is the roominess. This bag is an exceptional value; packs down well (with compression sack); and the temperature rating is true.
