Awesome Sleeping Bag
Hands down the best sleeping bag I’ve ever owned. The extra width is absolutely perfect for side sleepers!!
Swift YF20 - Norway
I actually use this exellent sleepingbag as my winterbag on my ski/tent/pulk trips in the Norwegian mountains. Have slept in it comfortably down to -15F. It all comes down to what i put between me and the snow. I keep a tripple layer under me. A 14 mm foam mat, a 70 mm Exped down mat, and a cut2size reindeer skin to top it up. All «ready to sleep» in an artic bedding(big flat bag) that is transported on the top of my pulk. I have not been cold ever. Love FF products.
I used my new 20 degree Swift for the first time recently on a week long float of Labyrinth Canyon in Utah. We had frost a few nights and way more dew than expected. Despite waking up with a wet exterior each morning after sleeping under the stars, none of the moisture penetrated the bag and after an hour in the morning sun it was good to go. Toasty warm every night. This bag is exactly what I was looking for.
Quality, spacious and warm sleeping bag
Had a great night sleep and as described has good space and is top quality.
Swift YF30 regular
I’ve not had it long and only had it out for a few days. It has been an unusually warm Oct, and even at night it has mostly been above 50F/10C. At those temps, it is too warm to have the bag fully zipped up. I think there was only one night where it got below 40F/4C, and it was very comfortable. So, while I can’t comment on what it will be like at 30F/-1C, my experience so far is that there is plenty of reserve capacity. I debated the YF20, but have another winter bag, and the YF 30 made more sense as a complement. I think I made the right choice and this will easily meet the majority of my 3 season needs. This is so much roomier then my old bag, it feels luxurious. I was considering the Penguin, but glad I didn’t. This is plenty big enough and I am 6’ 190lb. Beautifully made, everything looks to be of top quality materials, very puffy and at first you wonder how it will fit in the bag, but it does pack down nicely. Baring unforeseen circumstances, I don’t expect to ever buy another 3 season bag, so going with top quality is worth it and expect many years of comfortable sleeps outdoors.
