The Rab Solar Ultra 2 Sleeping Bag (-10C) is a synthetic sleeping bag for spring and autumn conditions. A key feature is the insulation. 100% recycled Stratus™ Eco insulation mimics the warmth-to-weight ratio of down but will keep you warm even when it's wet. Combine this with TILT Scrim Technology that blocks radiant heat, and you have a synthetic bag that's surprisingly low in weight and small in pack size for its warmth. The outer, lining, and insulation are 100% recycled.

Features:

• Internal TILT Scrim Technology on the upper reduces radiant heat loss
• Triple-layer concertina blanket construction on the upper for improved loft and warmth
• Elasticated internal quilting to draw insulation towards the user and eliminate cold spots
