BLACK ICE G400/700/1000 Mummy Single Goose Down Sleeping Bag

I researched the temperature of major cities in France and UK, if you like camping in summer, please choose G700, if you like camping in winter, please choose G1000. 

Of course, there are also higher-level G1300 and G1600, if you plan to go to the polar camp, you can choose. For ordinary camping, choose G700 and G1000, because tents can also reduce heat loss for you, followed by sleeping bags, and finally your clothes; If you choose G1300 or G1600 in not too cold weather, you will feel stuffy.

Of course, there are many outdoor brands in China, including 3F, Naturehike, The Free Spirits, Mobigarden in the tent field.Outdoor meals include ALOCS, and Fire-Maple in the field of camping stoves. For sleeping bags, Blackice is good. 

But Blackice focuses on the Chinese market and does not involve foreign trade. So there is almost no information on youtube and google. The best Chinese brand in the international market is Naturehike.

Regarding the sleeping bag fabric, they use GRAMART® from toray, a Japanese company with a history of nearly 100 years (Japanese companies have good research and development capabilities in the textile industry). This 15D fabric can significantly increase the bulkiness of the down and improve the thermal performance. The most important thing is light weight. I compared global brands with a price range of US$150-200. Toray’s fabric is indeed very good.

Generally speaking, 7D, 10D, 15D, 20D, 40D, etc. appear in down products; D is generally long fiber or silk, such as nylon, polyester fiber. Basically, the smaller the number, the more expensive the price of the same area and more Light weight. 7D＞10D＞15D＞20D＞40D.

However, it is not as small as possible when used in sleeping bags. Lightweight and tear resistance are the two directions of fabric development. For example, 7D and 10D fabrics may be filled with several hundred grams of down. When drying, storing, and washing, the fabric will have a certain degree of tearing effect due to its self-importance, such as the needle hole of the stitching caused by the tearing and stretching; if the use is not careful enough, it will be more likely to cause tearing. Crack damage, the result is velvet leakage. So Blackice chose 15D comprehensively.

What we see when the water is scattered into small drops on the clothing and then slips off, usually because the fabric used has been treated with water repellent. The water repellent treatment is actually a layer of special treatment covering the surface of the fabric, usually DWR (Durable Water Repellency) is added when the finished fabric is shaped to obtain durable water repellent performance.

The purpose of using DWR coating is that when water drops on the surface of the clothing, it can form small water droplets or slide directly from the surface of the clothing to prevent the fabric from absorbing water. At the same time, it also makes it easier to remove the oil stains attached to the surface of the clothing. Most waterproof clothing uses this DWR water repellent treatment, and the advantage of using DWR treatment is that the surface of the clothing does not absorb water, so as to ensure that the waterproof fabric can achieve good air permeability, so that the human body has a very good wear Feel.

Don’t be superstitious about bulkiness-is it warmer the higher the bulkiness?

The answer is: Under the premise that the space density of down does not exceed the critical point, the higher it is in the glass bucket, the warmer it is, but it may not be the same when the down is put in a sleeping bag. Because the design and production of sleeping bags need to solve two basic down problems, whether it is a penetrating structure or a standing lining structure, it is only a basic solution rather than a perfect solution. At present, there is no sleeping bag in the world that can perfectly release the natural state of down and restrain the fluidity of down.

But 700+fill is a good quality guarantee.

Finally, I want to compare some of the better tents sold in the U.K. and U.S. markets

Hyke & Byke these two sleeping bags are sold a lot on Amazon in the UK, but if you are willing to spend time comparing them, you will know that their prices are more expensive than the Blackice G series, but the Blackice G series will be better equipped.

Why? Because it is Amazon's high commission. I have also been an Amazon seller for 5 years. Amazon’s sales commission is 15%, and the remaining advertising expenditure + logistics costs account for 20%. This means that for a sleeping bag of £200, Amazon earns 200*0.35=£70. In order to maintain profit, the seller can only increase the price, and the buyer bears more expenses.

Hyke & Byke is just a young brand, and the brand cost is small. Let's take a look at rei's sleeping bag next. Everyone knows rei, if you convert it to US dollars, you find a $240 sleeping bag with a configuration of 600fill, 30D, duck and goose down, DWR, and heavier weight. This is still quite different from the G series configuration.

If you want to know more extreme configuration and design, Blackice Z series sleeping bag

Thanks.

Tips：

Blackice is the only sleeping bag brand in China that does not accept OEM processing. OEM means that in addition to producing its own brand, a factory also accepts the production of European or American brands and prints their logos. Because everyone knows that China is still the world's factory.

Why doesn't Blackice accept it? Because its own production capacity cannot meet the demand of the Chinese market in autumn and winter. At the same time, the top fabric sources are imported from Japan, and the quantity of fabrics obtained is limited, so the production capacity cannot satisfy the Chinese market, let alone OEM for other brands. As a dealer, we all make reservations in advance so that we have the opportunity to obtain inventory.

We check the official website http://www.blackice.cn/#/Material?_k=duvjla If you check Material Craftsmanship, small sleeping bag brands cannot meet the above standards.
