Does anyone have any experience with either of these bags? How accurate is the temperature rating, weight, and stuff size? Is the stretch system comparable to Mont-bell? Any concerns about durability?

Thanks,
Jess

Here is a review done on the Nitro 30 to give you some idea about quality

I have heard that the stretch system is the same as Montbell

From the BPL review it looks like the nitro is a lot tighter in fit than the montbell

Tight wouldn't be too bad, I'm pretty small. Last night I read as much as I could find on these bags as I had found a good deal on one in my size - long. I went ahead and pulled the trigger on it, good thing I did as it was the last one. I'll see how it does when it gets here. Really needed a new sleeping bag, my current 3.5 lb Lafuma was never cutting it, no matter how good of a deal I got on it.

Thanks guys for all the help.

The Nitro 30 has been my go-to bag for about a year now. I love it, one of the few UL bags that is warmer than its given rating. I am a slightly warm sleeper though, but still, at 30F I sleep in just my boxers, and at 25F I had on a light baselayer, and was very warm.

Its not the lightest bag in the world, after I removed the pad holding straps, the bag comes in at about 28oz, but that is light enough for me. Great bag, and I would imagine the Nitro 15 is just as well made.
