The award-winning Mythic Ultra 120 Modular cuts weight and bulk by only including insulation where it’s not already provided by your mat. The upper bag, and underside of the legs, is filled with ultra-high-lofting 900FP down and heat-reflective TILT, reducing radiant heat loss without a gram of unnecessary weight. Meanwhile, the lower bag hooks around the mat which insulates you from the ground.
With a tiny pack size and uncompromised comfort, it’s the perfect sleeping bag for long-distance trekking, bikepacking, and multi-day mountain runs.
The lightweight stitch-through construction is low-bulk, with the down strategically positioned to optimise warmth. Secure the bag onto your sleep mat using the back harness, while the insulated side baffles marry up to the side of the mat to keep cold spots at bay. We’ve chosen a diagonal zip to allow easy entry and exit, as well as plenty of ventilation on warmer summer nights. Stash clothing in the hood sleeve to create an ultralight pillow, further streamlining your kit list.
The Mythic Ultra 120 Modular is hand-filled in the UK to ensure that its down has never been compressed before use, retaining its loft for your first epic adventure.
Due to its construction, this bag does not meet the criteria for an EN test. Our sleep limits are based on our many years of experience, supplementary testing, and athlete and test team feedback. Head over to Rab Lab to find out more about the Rab Sleep Limit.
