NEW ULTRA DRY DOWN MODEL! Only 550 grams! The Micro McII is the smallest lightest sleeping bag we offer, it is an amazingly warm bag for such a small size.
The Micro series are our lightest weight bags, fully-featured and filled with 850+ Loft Eastern European Goose Down with WATERPROOFUltra Dry Down. These bags incorporate our 2D NanoShell providing the lightest most breathable water resistant shell.
With every Sea To Summit bag includes a "Down Batch Test Report" analysis certificate from the International Down Feather Laboratory (IDEL) to certify the superior loft of the down used in our Sea to Summit sleeping bags. You can be sure of the quality and fill within each bag.
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. 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.
Anti-bacterial and anti-microbial
Prolongs the life of your sleeping bag
In a world of technical brilliance it is remarkable that the performance of certain natural products have not been surpassed. Despite advances in modern fibre technology, down is still the best insulator warmth for weight, and is also the most durable sleeping bag insulation.
The problem with down is its vulnerability to water; moisture decreases the ability of the down to loft to its full potential and insulate, decreasing the warmth of your sleeping bag. Once down is damp or wet, it also takes a long time for it to dry out and effectively insulate again.
With the introduction of water-repellent ULTRA-DRY Down we have virtually eliminated the negative effects that moisture has on down. The ULTRA-DRY Down water-repellent treatment protects the down from external moisture and internal condensation.
ULTRA-DRY Down is a permanent* Nano-level water repellent polymer treatment applied to our high loft, high quality down. The Nano-thin treatment vastly improves our down s reaction to water without effecting its weight or loft performance. ULTRA-DRY Down retains over 60% more loft and absorbs 30% less moisture when compared with untreated down. Sea to Summit sleeping bags dry out 60% faster than bags with untreated down.
The Nano-level treatment also inhibits bacterial and microbial growth, which makes Sea to Summit sleeping bags more hygienic and improves their lifespan.
Sea to Summit sleeping bags, using ULTRA-DRY Down in combination with our already formidable 2D- and 3D-NanoShell system give you the best chance of sleeping warm and dry, day in day out throughout the worst of conditions.
With these technologies combined there is simply no reason to choose any other insulation or shell for your sleeping bag.
*No loss of treatment effect has been seen in over 14 wash cycles.
Loft is the volume for a given weight of down. It is used to describe the quality of down, relating directly to the insulating performance. High loft down is warmer for a given weight than low loft down. Higher lofting down will fill a larger volume of space for a given weight. As a result, less down weight is required to fill each baffle in a sleeping bag. This translates to a lighter sleeping bag. The most common measure of loft is called Fill Power. 850 Fill Power implies that one ounce of this down will loft to fill a volume of 850in3.
850+ Loft Goose Down
850+ Fill Power (Loft) Goose Down is the very best quality down available for sleeping bags. It provides the highest insulation for its weight and will last the longest. Sea to Summit 850+ Loft series bags are all filled with Eastern European Mother Goose 850+ loft down. Eastern European Goose Down is well renowned for its high quality, achieving the best loft, with the largest clusters that are strong and resilient, lasting for years.
650+ and 750+ Loft Premium Down
All Sea to Summit sleeping bags are sold with an International Down Feather Laboratory (IDFL) certificate that identifies the exact Fill Power of the down used.
We guarantee our sleeping bags are filled with premium down that exceeds the stated Fill Power in accordance to the International Down Feather Bureau (IDFB) standard.
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.

Heaviest sleep, lightest sleeping bagBy: Kurt Miller on 15 October 2015Big decision to spend this amount on a sleeping bag. Got every cent I paid for. Such a comfortable nights sleep and whilst the have removed a lot of bits to bring weight down, you don't notice as they are not important when on the trail.
