Rab Mythic Ultra 120 Modular Sleeping Bag - Regular

Introducing the Mythic Ultra 120 Modular Sleeping Bag, a revolutionary design that redefines lightweight and versatile performance for outdoor enthusiasts. Specifically crafted to complement the new Ultrasphere 4.5 sleep mat, this award-winning sleeping bag offers unmatched efficiency by providing insulation precisely where it’s needed, eliminating unnecessary bulk and weight. With ultra high loft 900FP down and advanced heat-reflective TILT technology in the upper bag and leg underside, it minimises radiant heat loss for exceptional warmth without compromise.

The lower section smartly hooks around your mat, utilising the mat’s insulation to keep you warm from the ground up. When paired with the Ultrasphere 4.5, the complete sleep system weighs under 700g yet delivers optimal comfort down to 0°C, making it the ultimate choice for thru-hiking, bikepacking, and multi-day mountain adventures.

Designed with practicality in mind, the bag features a low-bulk, stitch-through construction and strategically placed down for maximum warmth-to-weight efficiency. Side baffles align seamlessly with your mat to eliminate cold spots, while a secure back harness keeps the bag firmly in place. The diagonal YKK zip provides easy entry and exit while allowing adjustable ventilation for warmer nights. Plus, the hood sleeve doubles as an ultralight pillow when filled with clothing, streamlining your gear for minimal packing.

Hand-filled in the UK to ensure uncompromised loft and quality, the Mythic Ultra 120 Modular is compact, ultralight, and ready for your first epic adventure. Whether trekking, cycling, or running through the mountains, this bag is engineered to keep you warm, comfortable, and ready for the trail ahead.
