i do! works good, compacts a little less than down disco bags but overall it’s a good bag. I like the baffle at the top, really locks in the heat. edit: i want to add that i upgraded to the 15° disco down bag because i sleep rather cold in the backcountry, and my gf uses my old forte bag. she sleeps warmer than me and finds no issues with the forte. a majority of our camping is august in northern minnesota so temps around 40° at night

Another mummy bag in a mummy bag is underrated. I tried the sea to summit liner. What an absolute joke. I got a Nemo forte 20 that has a broken zipper. I put it in my other mummy bag. Absolute game changer. This probably isn’t helpful as you’re not carrying 2 bags. Sorry. Just shower thoughts

Not to convince you otherwise, I had the same problem, but like the sleeping bag. Nemo spoon shape was the answer for this side sleeper. Got the Forte 20.

I have the Nemo and cannot recommend enough. The extra room makes a huge difference for comfortable sleep and it keeps you nice and toasty. I have the Nemo Forte 20 and have used it comfortably in single digits multiple times- just don’t forget a bandana/scarf for your face!

I’ve got a Nemo Forte mummy bag that’s lasted me several years. It’s been heavily abused and other than a spot where my husky decided to attack my feet on our first camping trip, it’s still in great shape. I probably paid around $80 to $100 at an REI garage sale and still love it because it has vents to help regulate the temp, has a little extra room to adjust my knees and elbows because I’m a side sleeper and the hood/top section holds a pillow or extra clothing to turn into a pillow. Only downside is that it’s geared towards more petite people as I think the max height recommended is around 5’5”, anyone else is going to be sleeping outside of the bag.
