The Micro series are the lightest fully-featured bags from Sea to Summit, filled with 850+ Loft European Goose ULTRA-DRY Down. These bags incorporate the 2D NanoShell providing the lightest, most breathable water resistant shell. Designed with a contoured mummy shape, the Micro series are the lightest and most compact sleeping bags in their class. With a unique draw-cord opening at the foot for effective temperature regulation, the Micro series can be converted from an open duvet to a technical box foot mummy sleeping bag.
Focused on achieving ultra lightweight performance, this bag uses a YKK #5 zipper with micro anti-snag and quilted baffle construction to optimise down placement, resulting in the best warmth to weight ratio fully-featured sleeping bag. The form fitting Micro series uses a 55/45 fill ratio to insulate your core as the bag rotates with you throughout the night. A security pocket located inside the bag is easily accessible and is ideal for stowing electronics to preserve battery performance in cold conditions. The soft touch lining fabric is down proof by construction and highly breathable offering a comfortable sleep. The Micro series is our choice for cycle touring across the Pyrenees, adventure travel on the Inca trail in South America and fast & light backpacking in the Sierras.
