this is the one!
I expect quality from Mont-Bell, as I have for many years....I own the Alpine Light down sweater and always knew that they did down very well and that this bag would be good, very good. After several friends gave great reviews of the bag....I purchased it for my Guide/counselor/outdoor teacher son.
He is in the Wind Rivers this summer and sends back notes of how much he loves it and the great range of temps that it covers and how durable it is and how it gives him the much needed rest that you must have taking people out in the high country.
He is 6' ( we got a regular), 150 and sleeps cold....but, not with this bag.
I will expect it to last as long as my Sierra Designs down bag, that I bought in 1970..... But I will snag this bag from my son,to use, every time I can - which will not be much- I expect him to guard it.
If you afford it, get it....it is the 'one' !
