The Rab Solar Ultra 2 Regular is a three-season synthetic mummy sleeping bag designed for campers who need reliable warmth on cool nights. With a length of 215 cm and a shoulder width of 71 cm, it’s sized to fit most users up to around 185 cm tall, offering a snug profile that holds heat without unnecessary bulk.
Inside, you’ll find a dual-layer blanket of recycled Stratus synthetic insulation (60 gsm per layer), which traps warmth evenly and keeps insulating power even if damp. The outer shell and lining both use lightweight 20D Atmos™ recycled ripstop fabric with a fluorocarbon-free DWR finish, so moisture beads up and rolls off, helping you stay dry when the air turns misty.
In simple terms, “20D” refers to the thickness of the fine ripstop yarn (20 grams per 9,000 m of filament), while the ripstop weave adds a grid of reinforced threads to resist tears. The durable water repellent treatment helps keep the insulation dry by shedding surface moisture. The Solar Ultra 2 Regular carries comfort ratings of +2 °C for women and –4 °C for men, making it well suited to a broad range of spring, summer and autumn outings.
