First Impressions of Marmot Lithium Sleeping Bag, Short
The Marmot Lithium Sleeping Bag, Short is a standout product in the world of ultralight backpacking gear. Manufactured by Marmot, this 0-degree sleeping bag promises warmth and packability, essential for those who prioritize minimizing weight and maximizing performance in challenging conditions. It boasts sustainable ExpeDry water-repellent technology, a feature that immediately grabbed my attention.
I’ve spent countless nights in the backcountry, often pushing the limits of my gear in pursuit of that perfect alpine sunrise. My existing sleeping bag, while reliable, felt bulky and heavy, hindering my ability to move quickly and efficiently on long-distance treks. The promise of a sub-two-pound, 0-degree bag was incredibly appealing, a potential game-changer for my fast-packing adventures.
Upon unboxing, the Marmot Lithium Sleeping Bag, Short felt incredibly light and compact. The orange pepper/golden sun colorway is visually appealing, while the material felt soft yet durable to the touch. The included stuff sack compressed the bag to a remarkably small size, easily fitting into my pack with room to spare.
Compared to my older, heavier bag from a different manufacturer, the Marmot Lithium Sleeping Bag, Short presented a significant advantage in terms of weight and packability. I also considered the Feathered Friends Egret UL 20 and the Western Mountaineering UltraLite 20, both excellent options, but the Marmot seemed to offer a better balance of warmth, weight, and price. Initial impressions were overwhelmingly positive; I was genuinely excited to put this bag to the test.
Real-World Testing: Putting Marmot Lithium Sleeping Bag, Short to the Test
First Use Experience
I tested the Marmot Lithium Sleeping Bag, Short during a three-day backpacking trip in the High Uintas Wilderness of Utah. The elevation ranged from 10,000 to 12,000 feet, and nighttime temperatures dipped into the low 20s Fahrenheit. I slept in a lightweight, single-person tent for protection from the elements.
The bag performed admirably in the cold and slightly damp conditions. The ExpeDry water-repellent finish proved effective in repelling condensation from the tent walls. I remained warm and comfortable throughout the night, even when the temperature flirted with the bag’s 0-degree rating.
The mummy shape felt snug but not restrictive, and I appreciated the ample space in the footbox. No real learning curve was involved; it felt natural and comfortable right away. The only initial surprise was how quickly the bag lofted up after being removed from the stuff sack.
Extended Use & Reliability
After several weeks of use, including a week-long trek in the Wind River Range, the Marmot Lithium Sleeping Bag, Short continues to impress. The 800-fill-power down has maintained its loft and warmth, even after being compressed and stuffed repeatedly. There are no signs of significant wear and tear on the fabric or seams.
Maintaining the bag has been relatively easy. Spot cleaning with a damp cloth has been sufficient for removing dirt and stains. I plan to wash it carefully following Marmot’s instructions at the end of the season. Compared to my previous bag, the Lithium dries much faster, likely due to the ExpeDry treatment.
This bag has significantly outperformed my expectations, offering superior warmth-to-weight ratio and packability. It has become an indispensable part of my backpacking gear.
