The MegaLite 30F Sleeping Bag delivers ultralight comfort without cramping your style or your shoulders

What Our Gearhead® Experts Are Saying:


"I took the MegaLite 30F Sleeping Bag on a week-long thru-hike where every ounce mattered, and the wider mummy cut made a genuine difference in how well I actually slept compared to bags I've used at similar weights. The 850+ fill power down lofts fast even after a long day stuffed in the bottom of my pack, and the top collar seals in warmth without the pressure of a traditional hood cinched around your face."


Mile sixty on a thru-hike is not the place to discover that your sleeping bag is too narrow to turn over in. The Western Mountaineering MegaLite 30F Sleeping Bag was designed with that reality in mind, offering a wider mummy cut that gives side sleepers and restless campers the room they need without asking them to carry the extra weight that usually comes with it. At just one and a half pounds, it packs into a stuff sack small enough to drop to the bottom of any ultralight kit without rearranging your priorities.


Western Mountaineering filled the MegaLite 30F Sleeping Bag with 850+ fill power ethically sourced goose down arranged in continuous baffles that let you shift insulation toward colder zones as temperatures drop through the night. The 12-denier ripstop nylon shell is as light as it gets while still breathing well and handling the inevitable condensation of a backcountry camp. A top draft collar with adjustable draw closure seals cold air out at the shoulders without the weight of a full hood, and an insulated draft tube along the full-length YKK zipper closes off any remaining gaps. Made entirely in the USA at Western Mountaineering's San Jose facility, this is a bag built to last through years of serious use.
