In "Carry Light, Sleep Heavy Light Sleeping, Good Sleep", I mentioned Marmot's FP 900 three-season sleeping bag: "This is the lightest sleeping bag I have ever seen and used in the same temperature scale."
This is by no means an exaggeration. Because this sleeping bag has a high technological content, it is rare for my Gear Guy to put it down.
Its name is "æ°¦" and it belongs to the "Ultra Lite" series in the Marmot sleeping bag along with the other two sleeping bags "Hydro" and "Lithium". The position of this series is, "Applies to mild climate region Lightweight Climbing And Hiking Activity". It is truly unique to name these three ultralight sleeping bags with the lightest elements in the top three of the list of elements. They are also known as "the lightest in the world at the same level."
Two years ago, the colors of “Hydroâ€, “Strontiumâ€, and “Lithium†in the Ultra Lite series (black, blue, orange) and temperature scale (-1, -9, -18 degrees Celsius) and the “Spring/Summer 2003†upgrade "The temperature and color of the last three models remained the same, but the prices have risen a lot, because the progress of science and technology makes the weight of these three sleeping bags much lighter than the old models." Take "Lithium" as an example. Two years ago, "Lithium" (which is commonly known as the "Deep Doughstick") was filled with goose down at the time being the highest loft FP 800, and the surface anti-velvet fabric was Pertex ChainLink XD NP-150R. Liner-proof fabric is Gossamer Micro N 130R WR. At that time, spending more than 1,000 yuan to buy a bag with such a quality as the “Deep Fritter†would make a few owners take delight in it. I took one step too late and I did not get a “big oil stickâ€. I had to buy “氦†with the same material temperature scale of -9.
Marmot has taken the lead in the spring of 2003 to use today's highest goose down to 900 goose down as filling material for Ultra Lite series of three sleeping bags. In the spring of 2004, it began to upgrade the original two cold sleeping bags Col and CWM from FP800 to FP900. I didn't catch up with the new big fritters and I had to buy another new one.
After the upgrade of this series, in addition to the improvement of down quality, the anti-velvet fabric has also been greatly improved. The latest Pertex 20d Quantun fabric is used. The outer material is Pertex 20d Quantun Ripstop and the inner material is Pertex 20d Quantun Taffeta. More than ever, these fabrics are lighter, finer, and silky, weighing just under nine ounces per square yard. While the NP150NP's Pertex weighs 1.5 ounces per square yard, it is now secondarily used as a fleece-proof fabric for Marmot's 800 fluffy down sleeping bag.
When we study the technical parameters, it's annoying. Then I only comment on it from the sensory point of view:
The general size of the "æ°¦" is 183cm and it is 538g. Compression, the original XS compression bag is also slightly larger, you can completely find a tailor to reduce the size of the compression bag. In this way, after compression, diameter 18CM, length 25CM - what is the concept? This is smaller than a 4th football. It is shorter than a rugby. It's very exquisite. Take it out of the compression bag to release the down, and in a short while it will expand, grasp it in your hand, feel light if nothing, not like those inferior feathers have a "porcelain" feeling. It weighs only 822 grams, and my three-quarter sleeping bag of the same temperature standard MHW Storm Lite weighs 1300 grams, which is nearly a pound heavier than the "cockroach"!
The "Lithium" filling 767g, which weighs only 1133g, can also reduce the size of the original compression bag. It is a lot lighter than the Black Yak sleeping bag which is 900 grams full and weighs 1700 grams. The temperature scale is 3 degrees lower!
There is no perfect world, Marmot's UltraLite sleeping bag has two disadvantages:
First, the use of semi-long zippers rather than full-length zipper, and are left, not spliced ​​into a double sleeping bag may be second, the use of straight-type vertical lining, not as wave-like vertical lining can effectively prevent the pileless pile or pile down effectively.
Marmot recently added a new member to the "ultralight" series - the full length zipper "EQ Helium"
In order to achieve the "ultra-light" concept, and at the expense of a little comfort, the original design of the series of sleeping bags was originally intended. If you neglect to ignore those shortcomings, so comfortable and lightweight sleeping bag you go to find?
Take Pounds off your Pack. Even if you claim to be a "gorg," the backpack weight should really be higher before you travel each time.
