I write this review after just using the FF Osprey Long (I am 6'-6"/205#) "again" the night before last at Point Reyes National Seashore, CA: Night-time temp. was 35-37 degrees. I have now slept maybe 20 nights in the Osprey in Summer,Fall, Winter, and Spring

OK-the bag seems "almost" flawless. The Epic fabric sheds water as "if" it was waterproof. The 850+ goose down is baffled and dispersed so well that with the combination of sleeping in the bag with an insulated air-core mattress (2.5" thick) underneath, there are no cold spots. The bag fits well and I have enough room but not too much room. The Osprey packs small and it is relatively lighter than many of the bags I have had in the past both down and synthetic. The interior light Nanosphere feels like silk. The zipper is guided and kept from being bound inside by what looks like a stiff nylon strip with hot tape. The bag has a seriously thick, functional draft tube along the full length of the zipper. The hood drawstring works well for me. Overall the workmanship is flawless and I am proud to own this bag. Moreover, the bag is windproof, a handy tech-spec to have behind one in a tarp or open shelter.

Now, to talk about the "almost": the bag is too warm except for the coldest 1-2 hours of the night at around 3-5 AM. And then it is still very warm-it's just that I don't sweat in it then.I would say that the bag could very well be a good, warm 25 degree bag.

The other thing: the bag weighs 3.5 oz more than the weight it is advertised at on the website. When I called to order a bag because they hand make them per order, they said it would be 3-4 weeks for shipment, but they had one already made in red, new, if I wanted that one. I got it. I was shocked at how much loft it had when it arrived-between 5-6 inches and 9.5 inches of loft in the feet area. My girlfriend was so impressed that she ordered a 20 degree version(the Hummingbird) at the 6 ft length. Hers does weighs exactly per manufacturer's specs, and the down looks a little denser in places but not much different than my 30 degree Osprey. My only conclusion is that "maybe" it had 3 oz overfill in it and I got it without paying extra for it.
Anyway, the bag is too hot most times. I vent it with the zippers but that only works so well because 35 degree air is cold with no insulation and the bag is too much when it is Zipped, for the most part.

Am I going to send it back?---NO WAY. I am sure it will work well in the High Sierra for 3 season. I gave it a 5 because the bag is great although a bit too much for summer or really anything above 38 degrees, for me. I would say a good comfort range for this would be 20-35 degrees with the added 4.1 R-value of the insulated air-core mattresses, which most definitely adds to the bag's warmth rating too. But it is not just the mattress, I used the same mattress last March at Point Reyes when the Temp. was 35 degrees with a Marmot 40 degree synthetic bag with a 15 degree Thermalite liner, and I was cold, cold.

BTW-my girlfriend is very pleased with her Hummingbird--she sleeps colder, but she has sweat a few nights in hers too.

I guess a too warm bag is better than not warm enough. I can't imagine getting one of the 0 degree bags.
