EverLite – Ultralight Convertible Sleeping Bag

The EverLite is an ultralight convertible sleeping bag designed for warm-weather travel, layering, and adaptable outdoor use. At just 14.5 ounces, it’s one of the lightest and most versatile sleep systems in our lineup, combining premium materials with Western Mountaineering’s trusted USA-made craftsmanship.

Use it alone on warm summer nights, or unzip it fully to create a tapered down blanket—ideal for car camping, hut trips, or indoor use. You can drape it over a hammock for full-wrap insulation or pair it with another sleeping bag to add roughly 10°F of warmth in colder conditions.

The EverLite is filled with 850+ fill power goose down for ultralight insulation that compresses easily and lofts quickly. It provides efficient warmth while staying breathable and highly packable.

The full-length YKK zipper allows complete flexibility. Zip it up for a traditional sleeping bag feel or unzip it flat for maximum coverage and airflow. An open-ended footbox with an adjustable drawcord can be cinched closed for added warmth or left open for ventilation.

The minimalist design makes it a favorite among thru-hikers, fastpackers, hammock campers, and travelers who demand lightweight performance without sacrificing comfort.

Its compact profile and multifunctional design make it a smart warm-weather primary bag, backup bag, or layering piece for unpredictable conditions. Whether you’re sleeping under the stars, in a van, or at altitude, the EverLite adapts easily to a flexible sleep system.
