Sea To Summit MC II

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.

EN13537 Temperature Rating System

EN13537 is a European standard for sleeping bag temperature ratings.

Everyone sleeps differently; some people are very warm sleepers while others feel the cold easily. There are many factors that affect your warmth and comfort in a sleeping bag. An important factor is that you use a good insulating mat, so your body heat isn’t drawn into the cold ground you are sleeping on. Other factors include your tent or shelter, gender and metabolism, clothing, sleeping bag liner, use of the hood and your daily calorie intake.

Although the EN13537 standard does not identify a single precise temperature a tested sleeping bag is suitable for, it does provide an industry standardised temperature range that a typical user can refer to as a guide for the conditions their bag will be most comfortable in.

The EN13537 standard provides three temperature levels to guide a consumer in their choice

Comfort - the temperature at which a standard woman can expect to sleep comfortably in a relaxed position. If you consider yourself a cold sleeper use this rating to decide the coldest temperature the sleeping bag is suitable for.

Lower Limit - the temperature at which a standard man can sleep for eight hours in a curled position without waking. If you consider yourself a warm sleeper you can use this rating to decide the coldest temperature the sleeping bag is suitable for.

Extreme - this is a survival only rating for a standard woman. Between the lower limit and the extreme rating a strong sensation of cold has to be expected and there is a risk of health damage due to hypothermia. This is an extreme survival rating only, we do not recommend you rely on this rating for general use.
