Light and super warm

I wanted a lighter less warm bag than my snow bunting for a Northern Cascades trip. Perfect choice - super light weight and compact and very comfortable / warm at night. Temp rating spot on.

Beat sleeping bag ever!

I recently used my new Swift UL sleeping bag for the first time on a two night kayak camping trip to Blake Island in the Puget Sound. I camped in my Nemo Hornet tent and on my Nemo Tensor sleeping pad with my new Swift sleeping bag. I actually looked forward to going to bed each night and I stayed warm and dry all night. I especially liked the quality zipper and how it stayed in place at night when I moved. Definitely see and feel the high quality in this bag.

Swift ÚLTIMO 20 Wide

I am taking this bag on the PCT Oregon NOBO, so haven’t used it yet. However, it is definitely lighter than any bag I own, very compressible, and the right amount of room inside. Have to be careful with the zipper - tends to easily catch the edge of bag. So looking forward to utilizing it!

Great bag, still a little narrow for big shoulders

Bag is beautiful, feels like a 20 degree bag. It's still a little narrow for me, which I probably should have known because it's 64" in the shoulder and I have another bag that is 66" in shoulder and fits perfect. I do think the dimensions on the website are accurate. Would prefer a mummy bag but am returning and getting a Flicker wide for the extra width
