Mythic Ultra 120 Modular Down Sleeping Bag

The award-winning Rab Mythic Ultra 120 Modular Down Sleeping Bag cuts weight and bulk by only including insulation where it’s not already provided by your mat. 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. Rab have 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 Rab Mythic Ultra 120 Modular Down Sleeping Bag has been 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. Rab's 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.

What is TILT technology?: A radical, heat retaining tech that works like an emergency blanket reflecting heat back towards your body, while maintaining breathability and comfort. Boosting thermal efficiency, it keeps you warm when the temperature plummets.

Responsible Down Standard: The Responsible Down Standard (RDS) independently certifies down and feathers against animal welfare requirements and tracks it from farm to final product.
