First time use

4 day backpacking trip in the Smoky Mountains and the sleeping bag kept me warm every night! Very satisfied with my purchase.

Bought the extra length 7’ special order for my 6’8” height. Plenty of room in the shoulders and toe box. Very warm for a 2 lb+ weight. Typical FF exceptional build quality. I highly recommend.

The Best Down Bag I have ever owned

Fluffs up well and was very comfortable for a 5’10” 195lb individual in 35-40 degree temps.

    Great quality bag, but still a little chilly for me...

    This is a beautifully well-made quality bag that was tremendously comfortable to sleep in. Two caveats, the drawstring is a little bit cheap feeling and easy to get tangled in. That being said, I have no idea how it would be modified without adding weight. Additionally, I was cold when it dropped down to freezing, and was fully clothed with multiple layers and down pants/jacket. I still gave the bag 5 stars because I think this is an individual variation and simply something to be aware of for those individuals who run VERY COLD at night.
