Purchased in January 2026 from a mountaineering equipment store. It's the Rab Mythic Ultra 360 Long. I'm selling it because I accidentally bought the wrong model. Includes a storage bag and a stuff sack for carrying. Brand new, unused. Here's the product details from the manufacturer: The award-winning "Mythic Ultra 360" is one of the world's most advanced lightweight sleeping bags, designed and manufactured by in-house engineers based on 40 years of mountain experience. The outer fabric uses an extremely lightweight 10-denier ripstop nylon and is filled with high-quality European goose down with a fill power of 900+. But what's truly special is the lining. It features the world's first Thermo Ionic Lining Technology (TILT), which reflects heat back to the body by applying a titanium coating to the fibers, significantly improving insulation without sacrificing weight, breathability, or functionality.
