EXPED Ultra 3R LW Mummy is an ultra-light and compact three-season sleeping bag designed for hiking, trekking, bikepacking and other fast-paced, muscle-powered adventures where low weight, good packability and reliable insulation are crucial. The efficient mummy shape reduces both weight and pack size, while the LW size provides extra length for taller users - without compromising on functionality or comfort.
The base is constructed with SynMat Technology™, where recycled Texpedloft™ microfiber insulation is laminated directly into air passages for uniform and effective insulation throughout the sleeping surface. The structure reduces cold spots and provides stable warmth even when the temperature drops. With an ASTM-tested R-value of 2.9, the Ultra 3R is suitable for use down to temperatures around -5°C, making it a reliable choice from early spring to late fall.
The Ultra 3R LW Mummy is 7 cm thick and features EXPED's Comfort Cradle™ construction, with larger side channels to help keep the body centered on the surface during the night. The three-dimensional baffle structure increases stability, improves sleeping comfort and creates a smoother sleeping surface - despite the lightweight construction.
The cover fabric is made from recycled 20D ripstop polyester with TPU lamination and is bluesign® approved, ensuring a durable yet lightweight construction for active use. The chassis is equipped with EXPED's FlatValve valve, which makes filling and emptying quick and effortless. The included Schnozzel Pumpbag allows for efficient filling without moisture entering the chassis.
With its light weight and ultra-small package size, the Ultra 3R LW Mummy is a clear demonstration of EXPED's philosophy: maximum functionality, minimum surplus. A technical and carefully designed sleeping bag for the user who appreciates lightness, reliable insulation and equipment that works throughout the journey.
