I used this bag while camping in the Esmeralda Basin of Washington State in late May. I stayed comfortably warm in a long sleeved shirt and Snow Angel bottoms. My tent mate slept in her 20 degree TNF Cat's Meow bag and ended up being cold due to sweating in her layers. No sweating or cold for me in my Marmot Hydrogen, I was perfectly toasty. That's not the only plus. The bag in incredibly light and compresses down small compared the synthetic bag I have. I will definitely consider buying another Marmot down sleeping bag rated for colder temperatures.
