Swift UL 20/30

I have not used yet, but look forward to up coming backpacking season. Quality is excellent. Exactly as advertised. I was looking for a bag that was light and this is perfect.

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!
