For backpackers prioritizing low gear weight who don’t tend to get cold very easily, a sleeping bag rated 30 degrees Fahrenheit can function as their go-to for most three-season trips. And Marmot’s Hydrogen 30 remains one of the perhaps three highest-quality and warmest ultralight mummy bags at this temperature rating, as I affirmed sleeping in it for two nights on southern Utah’s Owl and Fish canyons loop in early May, four nights in Montana’s Beartooth Mountains in August, and five nights on the Grand Canyon’s Gems Route in mid-April.
