i've been hiking 2 to 3 times a yr for the last 20+ yrs and i have finally found the bag i'll use for the next 20. this is probably the 8th bag i've owned ( 1st down ). I.m 6'1" and 215 lbs and i never feel restricted in this bag. i used it down to 30 deg with just a light base layer on. no cold spots. great workmanship ( made in usa ). just buy it !!!!!
