User Review: Marmot Men's Trestles 15
I've used this bag at below 0 a few times without a tent, full length ground pad only. I slept in layers and was chilly (feet) in the morning, but everything worked out ok. I typically handle colder temps well, so keep that in mind. It's very comfortable between 15-30 with next to nothing on. I would recommend this to anyone who 'might' camp a few nights near zero, but mostly at 10 degrees or above.
