The Sea to Summit McIII is 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 temperature regulation, the Micro series can be converted from an open duvet to a technical box foot mummy 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. The soft touch lining fabric is down proof and highly breathable.

The down feathers are treated with Sea To Summit's Ultra-Dry Down treatment which adds water-reppelancy to the down and leading to faster drying times than untreated down. The bags are protected by the 2D NanoShell™ fabric, providing a very lightweight, highly breathable water resistant shell.
