Micro Sleeping Bag - MCIII

Micro Sleeping Bag – MCIII

The Micro series are our lightest fully-featured bags, filled with 850+ Loft Premium Goose ULTRA-DRY Down™. These bags incorporate our 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 drawcord opening at the foot for effective temperature regulation, the Micro series can be converted from an open quilt to a technical box foot mummy sleeping bag.

The Micro uses horizontal baffles, has a reshaped 3D snug hood, and a durable YKK® #5 zipper with micro anti-snag.

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 15D Nylon 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 and fast and light backpacking in the Sierras.
