This is a great sleeping bag

I had bought a left and right zip so my wife and I could get together when camping. We did not need more than 30 degrees because we live in Florida. I have slept in this bag on a sailboat on deck when it was blowing 20 knots and it was 40 degrees out... I was snug as a bug in rug. Used it with a Insulated Air Core 25 x 72 pad. There was also a cleat under my pad. The pack size is a little large considering I previously had a slumberjack 30. Living in Florida I needed synthetic.

Survived a 1700 mile bikepacking trip

I took this bag on the Baja Divide bikepacking route from Jan - March. My sleep system was bombproof and cozy on this ride, which was really important because the trip was so incredibly challenging. The bag also compresses enough to fit nicely on the handlebars of my bike. We only got below freezing once or twice, and I was toasty if I wore some clothes. The rest of the time I would sleep naked (cleaner than wearing my one riding outfit!) and the soft inner fabric was really nice and didn't get all sticky and gross like other fabric can. The fabric around the neck is nice to tuck yourself in and the pillow barn is a huge win. I'm super happy with how this functioned on this trip and I totally got my moneys worth - perfect bag for this kind of trip. My critiques include: there is no insulation between you and the ground other than your pad. This is not awesome if you end up in a situation where the ground is very cold (think November in Washington). There is also no pulling your knees up to side sleep because you are stuck to the pad - this is more of a personal preference although I love not falling off my pad. I've used this bag for at least 50 nights this year and it traveled in a tight sack for all of those days, so it is no surprise that the fill has been squished and it seems a bit less warm now. This really is just a summer bag, and it works great at those temperatures. Overall, massive bang for my buck and is made super well.

Bottom Line Yes, I would recommend to a friend

My partner is 6'3" and he fits with room to spare! We've never had a bag fit so well! Both little kids snuggled in too, haha. Like sleeping in a dream with the green sleeping pad. Love our bag and love the company!
