Great for ultralight outings where every ounce counts, the Zerogram Tuolumne SUL sleeping bag helps you save space and weight without skimping on warmth. Made of soft Pertex Quantum GL 7d fabric, the bag is stuffed with lofty 850-fill-power Polish white goose down that’s rated to keep you warm below 20 degrees Fahrenheit. Instead of the traditional side zipper, the Tuolumne SUL has a unique center zipper that’s easier to access and locks out side drafts. Finally, the stitched baffles have an ergonomic shape that prevents the insulation from shifting around while you sleep.
Founded in 2011 in Seoul, South Korea, Zerogram draws inspiration from naturalist John Muir and other 19th-century outdoor pioneers. The company’s philosophy is rooted in lightness—both in the way we pack our bags and the way we treat our planet’s resources. As a result, the product line features lightweight, minimalist, innovative designs for tents, sleeping bags, and other accessories. Zerogram takes its name from the idea of zero weight: “Though in theory, there is no material that weighs nothing, we dream of developing weightless equipment.”
