If you require a sub-zero warmth sleeping bag in the smallest possible size the Sea to Summit Mc III is your bag. The Micro series are our lightest weight bags, fully-featured and filled with 850+ Loft Eastern European Goose Down. These bags incorporate our 2D NanoShell™ providing the lightest most breathable water resistant shell.

Designed with a contoured mummy shape, the Micro series is the lightest and most compact sleeping bag in its class. With a unique drawcord 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 #3 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.

Form fitting, the 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, 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.

The quilted baffle construction provides consistent down density throughout the sleeping bag ensuring the down is where you need it most. Traditionally quilted sleeping bags relied on sewn through construction resulting in cold spots across the seams. Quilted baffle construction eliminates these cold spots, using lightweight 3 dimensional baffles to secure the down across both X and Y axis.
