Sea to Summit Micro MCIII Sleeping Bag
If you require a warm sleeping bag in the smallest possible size the McIII 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.
Box Quilted Mummy Convertible 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.

Our Verdict
There's real innovation in these sleeping bags, we've searched for a long while to find a high quality bag that will lay flat when required but these bags will do so much more, for example most bags of this weight have sewn through construction - the Micro series has baffled wall. Superb functionality endorsed by reviewers across the globe.
The Micro McII will compress to an amazing 2.8L in size!
The foot drawcord can be pulled in to create a mummy shape bag or opened to create an open ended rectangular sleeping bag
I’ve owned many different sleeping bags but I’ve never been entirely happy with any of them, they’ve always suffered a few inadequacies, some of which over time have really annoyed me – like snagging zips, poorly fitted hoods, cold spots, day-to-day growing dampness and difficult drawcords. So for a long time at Sea to Summit we have thought about this most basic outdoor necessity and wondered how, by using new materials and a fresh take on design, we could come up with a range of bags that eliminated those problems and delivered much better performance. Now at last I can confidently say we have done that!
To celebrate and mark our twentieth year, we bring you the most advanced sleeping bags available – they are lighter, warmer (for their weight), easier to use and combat moisture better than any other bags yet.
If the weight and performance of your gear is important to you, I believe our sleeping bags set a new benchmark.
